The soft spot on your baby’s head (fontanelle) is an area where the skull bones haven’t yet joined. The soft spot is covered by thick, tough tissue that protects the brain tissue underneath, so you needn’t worry about hurting it. If you sometimes notice slight pulsation of the soft spot, this is normal. You may also see small lumps, bumps, and irregularities in other areas of your baby’s head. These can also be normal. They are often caused by the shifting of the bones that make up the skull. These bones will eventually fuse completely together to make a smooth skull around eighteen months of life.
