Flat head in babies: initial guidance

What you can observe

Positional deformation is common, but the doctor must distinguish it from other causes. In the event of limited cervical mobility, paediatric physiotherapy and wake-up counselling are given priority.

The first landmarks in everyday life

Always keep the sleeping on your back, flat. When awakening, under surveillance, vary the interactions and propose short ground times adapted to the baby's tolerance. Do not use a flat head cushion.

Observe and seek early advice

A preference for turning the head on one side or flattening of the skull should be discussed with the professional who follows your baby. Report difficulty turning your head, sucking or interacting. Not all asymmetries have the same origin: the medical examination verifies in particular that it is not a situation requiring specific care.

Keep prevention recommendations at the forefront

Accompaniment is based on information from parents and, when indicated, paediatric physiotherapy. Evidence of a specific benefit of osteopathy remains insufficient to make it a reference treatment or promise a correction of the skull. No action shall force pressure on the infant's head.

Variant Safe Interactions

For each sleep, always lay your baby on the back, on a firm mattress and without a cushion. The time on the belly is only when it is awake, under surveillance, in sequences adapted to its tolerance. Offer stimulation on both sides and ask for advice if the rotation preference persists.
