The head of a newborn baby is ¾ the size of an adult’s, whereas body length is only ¼. Control of head muscles is not attained until the third month of age.
Hence the importance of helping babies to change posture to avoid deformities attributed to positional flattening
- Large, sleepy babies are more prone to positional deformities.
- First-born babies suffer parents’ inexperience.
- Second children may not get as much attention as the first.
Congenital muscular torticollis (CMT) affects a very large number of children with plagiocephaly. It is necessary to detect and treat it early.
- Prematurity is an important factor in post-natal development, and scaphycephaly is more frequent in these cases.
- Post-term born babies are more likely to present plagiocephaly and brachycephaly.
- Plagiocephaly is twice as frequent in boys than in girls.
- Brachycephaly is twice as frequent in boys than in girls.
- Scaphocephaly affects boys and girls alike.
- Positional plagiocephaly affects the right side more than the left.
- Brachycephaly affects large, sleepy babies more.
- Scaphocephaly is more frequent in premature babies.
- Multiple pregnancies.
- Large fetus (macrosoma).
- Post-term fetus.
- Narrow pelvis.
- Lengthy delivery.
- Uterine tumors (miomes…).
- Always sleeping on the same side: plagiocephaly.
- Always sleeping face-up: brachycephaly.
- Always sleeping with the head to one side: scaphocephaly.
- Torticollis (wry neck). Treatment to be given as soon as possible.
- Too much time spent badly seated in pushchairs or baby bouncers.
