We've put my baby to sleep on his back every night since the day we brought him home from the hospital. He likes to sleep on his back now and will not be placed on his side or on his stomach to sleep (I have also tried wedging him on his side, but this does not work). As a result of this, his head has flattened in the rear. Can you please tell me what to do about this and how it will affect the shape of his head as he grows older?
The bones of the head stay movable throughout infancy, so your son's head shape will continue to change for a while yet. He will eventually roll around in his sleep on his own and the flattening of his head will lessen with time. Be sure he gets lots of tummy time while he is awake and playing. His arm and shoulder strength will increase, he'll see the world from a different perspective, and he'll be encouraged to go after the interesting things that he sees. Carry him with you in a front pack if he is under 4 months, or in a backpack if older. His head will get more even pressure while he's awake and being next to you will reduce his risk of SIDS. The kids with flattened skulls who I worry about are the ones left all day in their cribs, waking and sleeping, without the chance to experience the world from a lot of different vantage points.
