The fontanel closes a little early in 8-month-old babies, but if the baby’s brain and nervous system are developing normally, it won’t be too much of a problem. Usually the fontanel closes between 1 and 1.5 years of age, but there are some variations, with some babies closing between 8 and 10 months of age, and some babies closing at 2 years of age. If the fontanel closes too early, the baby may have a small brain capacity or microcephaly, etc. You can take your baby to the hospital for a comprehensive examination and evaluation, and improve the cranial MRI and other related examinations, if the development is good, there is no need to worry about it, and if there is a dysplasia, you can follow the doctor’s instructions to give targeted treatment in a timely manner.
