Is it normal for a baby to have a heartbeat on it's head?

If the baby is a few months old (or younger), you may see a pulse on the top of the head at the 'soft spot', where the bones of the fontanel haven't yet sealed together after delivery. All babies are born with their skulls incompletely fused (to allow their heads to pass through the birth canal), but after several months (or more) the skull should close completely.

If you are concerned it is best to see a pediatrician.
