A soft spot If you gently run your finger over the top of your new bub’s head, you will notice there are some soft spots within his skull. There is no need to become alarmed, these are perfectly normal. In fact, these special sites (called fontanelles) are where your baby’s skull bones have not yet fused or grown together. The purpose of these ‘gaps’ is to allow room for his brain to grow, which is something that occurs quite rapidly and progressively throughout his first year of life. Your baby’s head will have two fontanelles. The anterior fontanelle is diamond-shaped and typically closes by around 18 months. The posterior fontanelle is the shape of a small triangle and is usually closed by the third month.
