Doesn back sleeping cause flat heads?
There is some suggestion that the incidence of babies developing flat spots may have increased with back sleeping. This is almost always a benign condition, which will disappear within several months after the baby has begun to sit up. Flat spots can be avoided by altering the back sleeping head position, such as turning the head to one side for a week or so and then changing to the other. Reversing the head-to-toe axis in the crib so the baby’s head can continually face outside activity (e.g., the door to the room) helps maintain this position.
