The US journal Paediatrics published study has uncovered that often parents make their babies sleep on their heads. They do so in order to avoid sudden infant death syndrome.

But the Canadian study has found that by doing this activity, children developed flat heads by the time they get two months old. The research was carried out by a group of researchers from the Canadian Mount Royal University.

Flat spots on head are also known as plagiocephaly. Study researchers were of the view that they have reached at the above given result after assessing 440 healthy full-term infants. Those children were evaluated who were born after 37 weeks of pregnancy.

Out of the total infants assessed, more than 46% infants were found to be spotting some form of flat spots on their heads. One of the other things that were noticed during the study was that 67% infants were having flat spots on the right side of their heads.

"With the Back To Sleep (campaign) and the overuse of car seats, and people not holding their babies like they used to, we've sort of rediscovered this problem with infants' head shapes", said Dr. Lisa Stellwagen, who is a neonatologist at the University of California.
