The first 1,000 days of life, from conception to early childhood, shape a child’s future health. Nutrition, lifestyle, environment, and parents’ well-being influence development through epigenetics and the microbiome, and healthy choices help build immunity and prevent disease.
A child's health doesn't begin at birth. It begins much earlier: during pregnancy, and even in the preconception period.
The first 1,000 days of life, from conception to around age two or three, are a crucial phase for a child’s development and future health.
During this period, factors like nutrition, lifestyle, stress, and environment have a profound effect on growth and well-being.
Scientific research, especially in the field of epigenetics, shows that external factors can influence how genes are expressed without changing the DNA itself.
In other words, the parents’ lifestyle can “switch on or switch off” certain genes in the child.
Among the most important factors:
These factors affect the risk of developing chronic diseases, metabolic disorders, and immune problems over the course of a lifetime.
The human microbiome is the community of microorganisms that live in our body (bacteria, viruses, fungi), and it plays an essential role in our health.
The gut microbiome, in particular, is the most important one and is often called the “second brain.”
Every microbiome is unique and develops based on several factors:
A balanced microbiome:
An imbalance (dysbiosis), on the other hand, can contribute to gut disorders, chronic diseases, and immune changes.
There are several stages where you can take concrete steps to build the foundations of your child’s health.
The parents’ health is the first step:
Taking folic acid (400 mcg a day) is recommended from the time you start trying to conceive and at least through the first trimester.
Medications should be used only when necessary and under medical supervision.
Antibiotics, in particular, can disrupt the microbiome of both mother and newborn.
The mother’s gut, oral, and vaginal microbiome directly influences the baby’s, starting in the womb.
It’s important to limit exposure to substances like BPA and PFAS (endocrine disruptors) by choosing carefully:
Vaginal birth promotes greater microbiome diversity (lactobacilli and bifidobacteria), while a cesarean (C-section) can result in less diversity (staphylococci, or bacteria from the environment or from health care staff, are often found)
Immediate contact between mother and newborn:
Breastfeeding promotes the growth of beneficial bacteria.
Formula may lead to lower microbial diversity.

Emotional factors matter too:
The first 1,000 days of life are a unique window for building the foundations of long-term health.
Through informed choices, you can have a positive influence on your child’s microbiome, immune system, and epigenetic mechanisms.
Investing in this stage means taking care of the future.
A session to approach starting solids with calm and confidence, learning about timing, methods, and practical tools to guide your baby through their first tastes.
A space for listening and presence before the day begins. A time for self-knowledge and deep listening: a weekly practice created together by two teachers who take turns leading, to wake up your muscles, let your breath flow, and nourish your inner calm every Friday morning.
Much more than a movement class: a small-group program for experiencing pregnancy mindfully. We’ll learn to listen to the body, ease tension, and use the breath as a valuable tool, discovering the personal resources to face birth with confidence.
Exercise and relaxation in pregnancy: benefits and practical tips
Why does raising children feel harder today? Perhaps because the parenting paradigm has changed, and with it the role of mothers and fathers. A short journey from a culture of authority to parenthood today.
Before you walk into the delivery room, there’s a special bag to pack: not with baby clothes, but with awareness, movement and practical tools. Discover how to bring body and mind together so you can play the leading role in your own birth.
There are no quick, universal fixes in breastfeeding. Aids can help, but only as part of a full assessment of the mother–baby dyad, weighing how, when, and why they are used, plus cost and ease of use. Often small changes to position or latch are enough.
