Nine months of pregnancy, followed by the first two years of life: the period known as the first 1,000 days is now recognised as one of the most defining of an entire lifetime. What a baby eats, what they feel, what they experience in contact with their parents — all of this leaves deep and lasting impressions, well beyond childhood.

But what actually happens during these 1,000 days? What are the key issues for your child’s health and development? And how, as parents, can you navigate this period with the right guidance and support? Mi&Ma offers you a comprehensive, accessible overview to help you approach these early days with a clear and calm mind.

What exactly are the first 1,000 days?

From conception to a child’s second birthday

The first 1,000 days begin at conception and end on a child’s second birthday. This period therefore covers nine months of pregnancy — approximately 270 days — and the first 730 days of a baby’s life. The definition was established by the World Health Organization (WHO) and has since been adopted by many governments to make their public health and perinatal policy evolve.

As an example, in France, the national First 1,000 Days programme, launched by the ministries responsible for health and early childhood, draws on a landmark report submitted in 2020 by an expert commission led by neuropsychiatrist Boris Cyrulnik^[1]. The goal: to make this period a priority for prevention and family support, by bringing together all those involved in the care pathway — from maternity units to Maternal and Child Health centers (PMI) and local healthcare professionals^[1].

Why is this period so foundational?

The reason the first 1,000 days attract such close attention is straightforward: science is clear on this point. Never does the human brain develop as rapidly^[1], and never does the environment have as great an impact on that development^[1], as during this window of life. The experiences a fetus goes through, and then a newborn, have a lasting influence on physical health, cognitive and emotional abilities — and even on health in adulthood.

This is not about putting pressure on parents or striving for perfection. It is simply an acknowledgement that the care, nutrition, quality of emotional bonding and security of the environment in the very earliest days of life lay solid foundations — for the child of today, and the adult of tomorrow^[1].

What happens to a baby during the first 1,000 days?

Remarkable development, week by week

From the very first weeks of pregnancy, a baby’s body and brain develop at a breathtaking pace. The nervous system takes shape, organs form, and the senses gradually awaken^[2]. By the time of birth, a newborn’s brain already contains billions of neurons, and the connections between them multiply at a rate unmatched at any other point in life.

After birth, this early development continues just as rapidly^[2]. Baby learns to recognize voices, faces and smells. They explore their environment, develop their motor skills, and begin to communicate long before uttering their first words. Every interaction, every moment of care, every shared experience with their parents feeds this development and helps build the foundations of their emotional and social life^[2].

Nutrition: a cornerstone from the very start

Among all the factors that influence a baby’s development during the first 1,000 days, nutrition holds a central place. From pregnancy onwards, what a mother eats has a direct impact on the fetus’ growth and the build-up of their nutritional reserves.

After birth, breast milk — when possible and desired — provides nutritional intake perfectly suited to a newborn’s needs, alongside its many benefits for the immune system^[3]. When breastfeeding is not possible, infant formula is a safe and appropriate alternative, formulated to meet the specific needs of each stage of a baby’s development.^[3] Then comes the introduction of solid foods, generally around 6 months, which marks a new milestone for both the child and the family.

Emotional bonding and environment matter just as much as nutrition

The first 1,000 days are not played out in the feeding alone. The quality of the relationship between parents and their child is equally important for their development^[4]. What specialists refer to as attachment — the sense of security a baby builds through close contact with their caregivers — is formed precisely during this period and has a profound and lasting influence on a child’s emotional wellbeing.

A stable, caring and reassuring environment is therefore a form of care in its own right. This does not mean being “perfect” parents — no such thing exists — but simply being present, attentive and responsive to a baby’s needs^[4]. And for parents going through difficult times, such as postnatal blues or a period of exhaustion, recognizing these signs and seeking support is a fully valid part of the journey.

And for parents — what does this period look like?

From pregnancy to coming home

The first 1,000 days are an intense time for parents, just as much as for their baby. It all begins well before the birth: prenatal appointments, birth preparation, prenatal interviews — all of these are opportunities to anticipate the arrival of a child and to voice questions, doubts and expectations.

Then comes the birth, the stay in the maternity unit, and the return home. Broken nights, new responsibilities, the profound shift in identity that comes with becoming a parent: all of this can weigh on you, even when everything is going well^[5]. Postnatal blues, experienced by one in five new mothers in the days following birth, is a common illustration of this. It should neither be dismissed nor be a source of guilt: talking to a healthcare professional is always the right step^[5].

Who can you turn to for support?

The good news is that parents are not alone. In many countries, there are services, professionals, and resources available to support families throughout a child’s early years.

Depending on where you live, this support may be provided by a range of professionals, such as maternal and child health services, midwives, pediatricians, general practitioners, or local family support organizations. These professionals offer regular follow-up, personalized advice, and guidance from pregnancy through the child’s first years.

At the same time, more and more resources are available to help parents in their daily lives: reliable websites, educational materials, helplines, and mobile apps. These tools provide practical advice, clear guidance, and help families find professionals or services close to home.

Getting informed and building a support network from the very beginning can make this period more reassuring, with guidance tailored to both the parents’ and the child’s needs.

The first 1,000 days of your child’s life are an intense time — sometimes turbulent, but also full of discovery. From conception to your baby’s second birthday, every day matters, every moment of care matters, every shared experience matters.

Because every baby is unique, and every parenting journey deserves to be supported with gentleness, expertise and warmth, Mi&Ma is committed by your side. Because little moments deserve big care.

Benefits of breastfeeding: a natural choice for your baby

Breastfeeding is now recognised as the nutritional gold standard for infant feeding. Numerous international scientific studies and recommendations from health authorities, such as the World Health Organization (WHO), highlight its major benefits for the baby’s health, but also for the health of the breastfeeding mother. 

For many women, the decision to breastfeed also raises practical, emotional and organisational questions. Having access to reliable information, tailored advice and caring resources enables mothers to make informed choices in line with their experiences, their needs and those of their baby. 

In this article, we take a clear, evidence-based look at the benefits of breastfeeding, while emphasising that every parenting journey is unique! 

The best food to meet babies’ specific nutritional needs

Breastfeeding means feeding an infant with the milk naturally produced by his mother. According to WHO and UNICEF, it is recommended to: 

• Start breastfeeding within the first hour after birth 
• Practice exclusive breastfeeding for the first 6 months of life 
• Continue breastfeeding alongside a varied diet up to 2 years of age or beyond ^[1].

These recommendations provide a reference framework, but they must always be accompanied by personalised guidance, particularly to help mothers breastfeed in good conditions, at their own pace, and according to their personal or medical situation. 

Breast milk alone provides all the elements needed for an infant’s healthy development during the first six months of life: antibodies, vitamins, minerals, trace elements, carbohydrates, fats and proteins, in the right proportions. As a truly “living” food, it is constantly evolving to keep pace with your child’s growth. Its composition changes during a feed, becoming progressively richer in fats as the breast empties or when feeds are close together. It also varies according to the time of day, and naturally adapts over the weeks and months. ^[2] 

It is the only food which composition so perfectly meets the baby’s specific nutritional needs, at every age. 

What are the benefits of breastfeeding?

The benefits of breastfeeding for the baby

An essential support for the young child’s immune system

Many studies show that breastfed children have a reduced risk of respiratory and gastrointestinal infections, particularly during the first months of life. 

Researchers have also observed a decrease in the risk of ear infections, severe infections and infant mortality in breastfed children. ^[3] 

But the benefits of breastfeeding for a child’s health do not stop at early infancy. Over the longer term, scientific data associate breastfeeding with: 

• A reduced risk of overweight and obesity 
• A lower risk of type 1 diabetes 
• Better performance on cognitive and developmental tests. ^[3]

The benefits of breastfeeding for the mother

Breastfeeding has also been shown to provide physiological benefits for the mother: it supports postpartum recovery and is associated with a reduced risk of certain cancers, particularly breast and ovarian cancer, as well as a decreased risk of type 2 diabetes.^[4] 

For women, these benefits form part of a global approach to maternal health, which also includes the importance of postnatal care, rest and appropriate support throughout the breastfeeding period. 

A positive impact on the mother–child bond

Beyond its biological aspects, breastfeeding promotes skin-to-skin contact, emotional security and attachment bonding between mother and child, all of which are essential for the baby’s emotional development. 

Did you know?
Oxytocin, often referred to as the “bonding hormone”, is released during childbirth, milk ejection and moments of contact such as skin-to-skin or gentle touch. It plays a key role in creating and strengthening the emotional bond between mother and baby. 

To support calm, confident breastfeeding, it is recommended that mothers have access to a reassuring environment, appropriate care and professional advice (midwives, lactation consultants, healthcare professionals), both in the maternity ward and after returning home. 

Breastfeeding and complementary feeding

From around 6 months of age, infants’ nutritional needs begin to change. The gradual introduction of complementary foods becomes necessary, while continuing breastfeeding: this is the stage of complementary feeding. 

WHO notes that breast milk can continue to cover: 

• Around half of energy needs between 6 and 12 months 
• Up to one-third of energy needs between 12 and 24 months.^[1]

Weaning: a personal choice to be supported gently

Weaning refers to the gradual reduction or complete cessation of breastfeeding. The decision about when to wean is individual and depends on the mother, the child and the family context. Mixed feeding can also be introduced: this means keeping some breastfeeds while complementing intake with an infant formula adapted to the baby’s age. 

For some women, weaning can be a sensitive stage, both physically and emotionally. Being supported, well informed and guided towards suitable solutions helps mothers go through this transition with more confidence and peace of mind. 

When weaning is desired, it is recommended to offer age-appropriate foods, focusing on variety, the quality of ingredients and respect for the child’s nutritional needs. 

Milk, whether breast milk or infant formula, remains a key component of a child’s diet up to 3 years of age. 

At the weaning stage, families therefore need to rely on infant milk formulas designed to gently support this dietary transition.

Baby’s complementary feeding: supporting the discovery of foods, from 6 months

Food diversification is a key stage in an infant’s development. After several months of exclusively milk-based feeding, babies gradually begin to explore new foods, textures, and flavors. This transition reflects the natural evolution of their nutritional needs, physiological abilities, and motor and sensory development.

When should food diversification begin? Which foods should be introduced first? How can parents respect their baby’s rhythm while ensuring safety and nutritional balance?
In this article, we provide clear guidance based on international recommendations, to help families navigate this stage with confidence and peace of mind.

Complementary feeding: what does it really mean?

Complemetary feeding (or food diversification) refers to the gradual introduction of foods other than milk into a baby’s diet. It marks the transition from an exclusively milk-based diet to a more varied one, while keeping breast milk or infant formula as the nutritional foundation.

The first foods offered are usually vegetables and fruits, followed progressively by starchy foods and protein sources. Textures evolve gradually, from smooth purées to mashed foods and then to small, soft pieces, supporting the development of chewing skills.

This period represents a major learning phase: babies develop their sense of taste, refine their oral motor skills, and begin to build a new relationship with food.

Why is complementary feeding such an essential stage?

Meeting the baby’s evolving nutritional needs

From around 6 months of age, an infant’s nutritional requirements increase. Certain nutrients—such as iron, zinc, and some vitamins—can no longer be supplied in sufficient amounts by milk alone. Introducing complementary foods helps meet these growing needs while supporting overall growth and development.

Encouraging taste development and healthy eating habits

The first years of life are a critical window for shaping food preferences. Repeated exposure to a wide variety of foods and flavors—even when initially refused—supports better long-term acceptance of foods.

A relational and social experience

Food diversification is not only about nutrition. It also takes place within an emotional and social context: babies observe, imitate, and gradually share mealtimes with their family. These interactions help build a positive and confident relationship with food.

When should food diversification begin?

The World Health Organization (WHO) recommends exclusive milk feeding until 6 months of age, followed by the introduction of appropriate complementary foods, while continuing breastfeeding up to 2 years of age or beyond.^[1]

Introducing complementary foods before 6 months has not been shown to provide nutritional benefits and may increase the risk of gastrointestinal infections. Conversely, delaying diversification beyond 6 months may increase the risk of nutritional deficiencies, particularly iron deficiency.

How can you tell if your baby is ready for complementary feeding?

Beyond age, several signs indicate that a baby may be ready:

• He can hold his head up steadily and sit with support,
• He shows interest in foods eaten by adults,
• He spontaneously brings objects to his mouth,
• The tongue-thrust reflex (pushing food out with the tongue) has diminished.

These signs reflect sufficient neuromotor maturity to handle textures other than milk.

The main stages of food diversification

 From 6 to 8 months: first explorations

At this stage, milk remains the main source of nutrition. Solid foods are offered in small amounts, primarily for sensory discovery, with 2 to 3 meals per day.^[1]

Textures should initially be smooth and homogeneous. Well-cooked and blended vegetables (such as zucchini, carrot, or pumpkin) are often introduced first, followed by cooked fruit purees (without added sugar). Quantities are modest and increase gradually according to the baby’s appetite.

Textures then slowly evolve toward thicker purees, mashed foods, and soft preparations. New food groups are introduced progressively:

• Starchy foods (rice, pasta, legumes, etc.)
• Animal proteins (meat, fish, egg, always fully cooked), in small quantities

Did you know?
Fats play an essential role in a baby’s diet, particularly as a source of essential fatty acids (such as omega-3 and omega-6), which are crucial for the development of the brain, nervous system, and vision. From the very beginning of food diversification, adding a small amount of raw fat (such as a suitable vegetable oil like rapeseed oil or a balanced oil blend) to purées and meals helps meet these specific nutritional needs. Contrary to common belief, fats should not be restricted in young children—they are vital for healthy growth and overall development.

From 8 to 23 months: discovering pieces and structuring meals

Around 8 months of age, it becomes important to start offering small, well-cooked, soft pieces of food. Gradually, as chewing skills develop, these pieces can become less soft.

Meal patterns also begin to take shape, with 3 to 4 meals per day for babies aged 9 to 23 months, plus one or two additional snacks if needed.^[1]

Quantities and rhythms: following the child is key

There is no universal portion size suitable for all babies. Appetite varies depending on age, growth, and developmental phases. The goal is to offer balanced meals while respecting hunger and fullness cues.

Forcing a child to eat can disrupt their natural ability to self-regulate. In contrast, a calm and pressure-free environment supports a healthy relationship with food.

An important indicator to monitor remains the child’s growth curve, with regular follow-up by a healthcare professional.

How can food allergies be prevented?

Recent scientific evidence shows that delaying the introduction of allergenic foods does not reduce the risk of food allergies. It is now recommended to introduce them gradually, from the beginning of food diversification, in age-appropriate forms.

Foods such as kiwi or strawberries, as well as other common allergens like egg, peanut, and tree nuts (almonds, hazelnuts, etc.), can be offered in small quantities and in adapted forms (for example, as powders or purees), while carefully monitoring tolerance.

A successful complementary feeding with Mi&Ma!

Food diversification is a gradual process that supports a child’s overall development. Starting from 6 months, it helps meet evolving nutritional needs while fostering the learning of tastes and textures. By respecting your baby’s rhythm, offering a wide variety of foods, and keeping milk as the foundation of their diet, you help build the foundations for a calm and lasting relationship with food.

Discover our products designed to support food diversification!

Safety also relies on preventing choking risks: babies should always eat seated upright, under constant adult supervision, with foods that are well cooked and presented in textures appropriate to their chewing abilities.
