Question
My baby is 2 months old and has a triangular dip on the back of her head. The area is surrounded by bones. Is this the anterior fontanelle? What impact might there be if I accidentally touch it while holding her to feed her (through a thin blanket)? My baby recently sleeps for long periods, about 20 hours a day, with each sleep lasting over 2 hours. She also occasionally dry heaves. What could be the cause?
Answer
The dip on the back of the baby’s head might suggest an open anterior fontanelle, which usually closes within 1-2 months after birth. If it remains open, calcium supplementation is recommended. It’s advised to focus on digesting cod liver oil and calcium, and to expose the baby to sunlight more often. The long sleep duration is a normal occurrence at this stage. The dry heaves may be related to an underdeveloped gastroesophageal area, and there is no need to worry. These are my suggestions for the question ‘What’s the cause of a triangular dip on a baby’s back of the head?’ I hope this helps you, and wish you and your baby good health!
