I just got back from DS's 6-9m developmental check with the community health nurse and I'm a little worried... He's going great guns in all areas, bless him, but she said his fontanelle (the anterior one - on top of this head) is quite small, and that it's a little early for it to be closing yet. She wasn't really concerned and said to bring him back in a month's time to have his head measured again to make sure it's growing at the right rate (he's right on the 50th percentile for all his measurements so he's fine ATM).
I asked a few more questions, and she said the issue is that if the skull bones fuse too early his brain won't have any room to grow, but it's actually really common for babies' fontanelles to close early (but not fuse). Naturally, I couldn't help asking then about the worst case scenario, ie what if his head didn't keep growing... She said if that was the case - and it's really uncommon - that he'd have to have cranial surgery to make more room for his brain to grow.
So, what did I do? I didn't listen to her assurances and went straight home to consult Dr Google. And here I am now, freaking out!! But that said, I read what Robin Barker had to say on the matter in 'Baby Love' and she said that fontanelle size varies tremendously from baby to baby and they can close any time from 4-18m.
Has anyone else's LO had their fontanelle close early? Looking for some reassurance from other mums please!!
