Hi my ds is 22 months and his fontanelle is still open. About 20p piece sized. Ive gotten myself overly worried by googling. Should I talk to my health visitor or wait until his 2 year check. If it's relevant he hasn't said any real words yet he babbles but no real meaning he's also very shy and runs away if other children try to play with him. Any advice or if your little one took a long time to close aswell thankyou in advance.
