Osteopathy and childhood: what are the benefits to support your child's development?
5 July 2026
The early years of life are an extraordinary period of discovery, learning and change.
Babywearing changes parents' lives in the first few months. But faced with the multitude of models available — pre-formed baby carrier, wrap, kangaroo t-shirt, sling — it's hard to know how choose an ergonomic baby carrier which is truly suitable for baby and parents. This guide reviews everything you need to know before buying. 👶
One ergonomic baby carrier is a carrying device that respects the infant's natural physiology. The fundamental difference compared to a conventional baby carrier: the position in M.
What is the M position? Baby is positioned with their hips higher than their bottom, knees bent above the pelvis, forming an «M» when seen from the front. This position — identical to that of a baby naturally carried in arms — is recommended by paediatricians and orthopaedists because it respects the development of the hips and spine, which are still forming.
Conversely, non-physiological baby carriers (where the baby hangs by the crotch with dangling legs) can promote hip dysplasia. The International Hip Dysplasia Institute explicitly recommends the M position for all baby-wearing devices.
That is the deal-breaker. Check that the baby carrier seat supports the baby from the backs of the knees to the buttocks — not just the crotch. The wider the seat, the better the hips are supported.
The backrest must support the baby's entire spine, respecting the infant's natural C-shaped curve. For newborns (under 4 months), the head must be supported — either by a built-in headrest or by a newborn insert.
A good one ergonomic baby carrier distributes the baby's weight across the shoulders AND hips — never just the shoulders. The wide waist belt is essential for carries of more than 30 minutes. Padded, adjustable shoulder straps make it easy to share between two parents of different builds.
Some models start from birth (with an insert or newborn reducer), others from 3-4 months. Adaptable models accommodate up to 15-20 kg — which is 3-4 years. Check the weight limits before buying.
A baby carrier that isn't used because it's too complicated to put on is useless. The pre-formed baby carrier with buckles and adjustments is the simplest. The baby wrap requires learning. The kangaroo t-shirt is the most intuitive of all.
Light cotton for the summer, breathable materials (mesh) to prevent overheating, fleece lining for the winter. Avoid thick synthetic materials in summer — baby cannot regulate their temperature well yet.
This is the most popular format. Waist belt + padded shoulder straps + adjustable buckles. It goes on in 30 seconds, is easily shared between two parents, and is suitable for long walks. The version with integrated storage is particularly practical for outings without a changing bag.

Babywearing revolution: a fitted garment with a built-in pocket. Ideal for skin-to-skin contact, the early months, and quick outings. Unisex, machine washable. The easiest to use of all babywearing systems — no knots, no buckles.

One shoulder, two rings, a long tail of fabric. Lighter and quicker to put on than a standard wrap. Ideal for frequent transfers (taking baby out, putting them back in). Less recommended for long carries or heavy babies — the weight is on one side.

Designed for babies who can sit unaided (from around 6 months). It frees up the parent's arm while keeping baby in a side-lying position. Perfect for short distances — at the doctor's, at the market, on the stairs.

Skin-to-skin contact is a priority. A kangaroo T-shirt or stretchy wrap are ideal. If you choose a structured baby carrier, check that it is suitable from birth (with an insert) and that the head is supported. Facing-in position only at this age.
Baby is starting to hold their head up on their own. The pre-formed baby carrier without an insert becomes usable. Some babies enjoy the outward-facing position — check that the model offers it AND that it properly supports the hips in an M position.
Baby is getting heavier and heavier — the waist belt and wide shoulder straps are becoming essential. Back carrying (for models that allow it) relieves the parent's spine for long distances.
Whichever solution you choose, check these 5 points at every babywearing session:
From birth for models designed for this purpose (kangaroo t-shirt, stretchy wrap, pre-formed baby carrier with newborn insert). Always check the minimum weight indicated by the manufacturer — generally 3.5 kg.
There is no medical limit to carrying in an ergonomic position. Some parents carry their baby for several hours a day without issue. Listen to your body — if you feel tension in your back or shoulders, adjust the setting or take a break.
No, on the contrary — carrying in a physiological position is beneficial for the development of the spine and hips. It is NON-ergonomic carrying (dangling legs) that presents risks. A ergonomic baby carrier correctly used is approved by paediatricians.
Both are complementary. The pushchair is practical for long outings, shopping, flat terrain. The ergonomic baby carrier is essential for stairs, public transport, difficult terrain — and for babies who need physical contact to calm down.
A simple test: your baby should be high enough for you to kiss them on the forehead without having to bend your head down. Their knees should be higher than their bottom. Their back should be curved in a C-shape (not straight). And you should be able to slide a flat hand between your tummy and your baby’s back.
PetitMaxou offers a selection of ergonomic baby carriers M-position approved: preformed carriers, pouch slings, wraps and ring slings for all ages and uses. Free delivery throughout the EU, 14-day returns.
