At what age does the fontanelle close?

Hi doc. A friend took her son for a general check-up at 1 year to the paed, who noticed that the baby's fontanelle/skull on his forehead, but not on top of his head, had grown closed. Baby then had to undergo surgery to open the fontanelle on his forehead. He is a happy, health baby and there were no signs that anything was amiss, except that at 1 year he is not even crawling yet. Luckily the op was a sucess but I am now paranoid about this happening to my baby also (15 months). What signs should we look out for? Your advice will be appreciated.

It sounds as if you describe premature closure of the fontanel and sutures of the scull (craniosynostosis), but luckily this problem occurs very rarely. The front fontanel usually closes by 15-18months. The most important thing is that your child develops normally and that his head circumference increases as expected.

Wow, that is a big word!! It could be - I'm not sure of the name, all I know is that it was the skull on the baby's forehead that had to be surgically reopened/separated. Could this happen by my 15 month old - what symptoms or signs should I look out for.

Are you sure it was not "Craniosynostosis" that was repaired and not a fontanelle?
