Flat Head Syndrome (Plagiocephaly) in Babies

Plagiocephaly (flat back of head or asymmetric head shape) affects nearly half of all babies in the first months. In most cases, it is a positional deformity that resolves with simple measures like tummy time and repositioning. Rarely, craniosynostosis (premature suture closure) is the cause, which requires medical evaluation.

Possibili Cause

  • 1Back sleeping — lifesaving (SIDS prevention), but common cause of flattening
  • 2Preferred head position to one side (positional preference/torticollis)
  • 3Too little tummy time while awake
  • 4Too much time in car seat, bouncer, or carrier (hard, flat surface)
  • 5Prematurity (softer skull bones)
  • 6Very rarely: craniosynostosis (premature closure of a skull suture)

Cosa Puoi Fare

  • Regular tummy time while awake — possible from day 1, gradually increase several times daily
  • Regularly change head position during sleep (alternately to left and right)
  • Offer stimulation from the non-preferred side (toys, talking, light)
  • For torticollis: physiotherapy with targeted stretching exercises
  • Helmet therapy (cranial orthosis) only for severe deformity from 4-6 months — medical recommendation needed

Quando Andare dal Medico?

  • Head shape does not improve despite consistent repositioning (after 2 months)
  • Palpable ridges or bumps along skull sutures
  • Head circumference not following growth curve
  • Fontanelle closes notably early (before 6 months)
  • Asymmetry getting worse instead of better
  • Baby cannot turn head to the other side at all (fixed torticollis)

Note per Fascia d'Età

Most positional head deformities develop between months 1 and 4 and resolve on their own by 12-18 months as the baby sits, crawls, and lies less on the back of the head. Helmet therapy (if needed) is most effective between 4 and 8 months when skull bones are still mouldable. After 12 months, helmet therapy is usually no longer effective.

Domande Frequenti

Should my baby sleep on their stomach to fix the head shape?
NO! Back sleeping is NON-NEGOTIABLE — it saves lives and reduces SIDS risk by over 50%. A slightly flat back of the head is a cosmetic issue that usually resolves itself. SIDS is fatal. Instead: lots of tummy time while AWAKE under supervision.
Does my baby need a helmet?
The vast majority of babies do NOT need a helmet. Consistent repositioning, tummy time, and possibly physiotherapy are sufficient in over 90% of cases. A helmet is only considered for severe, persistent deformity and must be recommended by a paediatrician or paediatric orthopaedist.
Can an asymmetric head harm my baby?
Positional plagiocephaly is almost always purely cosmetic and does NOT affect brain development. The skull bones adapt, the brain has enough space. Only with craniosynostosis (premature suture closure) can intracranial pressure increase — that's why medical differentiation is important.
