Deformational / positional plagiocephaly is flattening of a baby’s skull, typically considered to be a cosmetic condition.
Parents are recommended to see their GP, a paediatrician or a qualified health professional early if there are any signs of flat head / plagiocephaly or torticollis / wry neck for this to be checked.
A qualified paediatric osteopath will also check your baby’s neck and spine and may give exercises and home care advice.
Remember, most babies with plagiocephaly are absolutely fine, they just have a slightly wonky head from lying on their back for long stretches.
