Sleeping position and head shape.
My month-old son always sleeps on the right side of his head. When I put him down on the other side he rolls over. I've noticed that his head is flatter on the left hand side than the right, should I be worried about it? What can I do about it?
Nobody's head is symmetrical, don't worry too much.
It is very common for a newborn baby to have a lumpy or oddly-shaped head, as the skull is still soft. It may have developed this way during pregnancy due to his position in the womb, or during birth, if you gave birth naturally. It could also have occurred during the first few days of his life, if he slept in the same position. Once your son starts sitting up, around the age of seven months, his head will even out.
