Giving an infant tummy time is essential – and not just because of flat-head syndrome. Yes, putting an infant on his tummy more often will limit the pressure on the back of his head, but it will also help to develop the baby’s neck and chest muscles, which is imperative for proper development. All this said, do not put a child on his tummy to sleep. Tummy sleeping has been linked with an increased risk of SIDS (Sudden Infant Death Syndrome), and should be avoided. Even if putting an infant to sleep on his stomach would reduce positional plagiocephaly, SIDS is a far worse risk.
