It should be noted, however, that it is designed to prevent Flat
Head Syndrome rather than correct an existing issue.
Developmental delays have been noticed in roughly 22 % of infants who spend the majority of time on their backs, and doctors believe that tummy time, time in slings or carrier pouches, and the use of seats which require infants to use their neck and back muscles
rather than providing a
head rest may prove beneficial in preventing container
syndrome as well as related motor skill and developmental delays.
