Question: What are the two fontanelles seen on a newborn’s head? When do they close?
Answer: There are two fontanelles or “soft spots” on a newborn’s cranium. The posterior fontanelle closes within 1–2 months after birth. The anterior fontanelle (at the top of the head) closes after about 9–18 months.
Bulging fontanelles may be a sign of increasing intracranial pressure, while sunken fontanelles may indicate depression.
