My son is 21 months old, always on the go and constantly active but he doesn't say many words at all, maybe 10 at most! I have brought this up with health visitors but she just keeps fobbing me off and says he is saying enough words. In my gut I feel there is something more going on, I feel he is possible autistic, he doesn't respond to his name all the time maybe 70% of the time, he goes into his own little world sometimes but loves to play with kids, dances, points, claps, he is a happy little boy. I don't know if I am overthinking but I have two older girls and they were talking about understanding a lot more at this age. Anyone else's little ones like this? I just want to get him help if he needs it. I am so anxious over it.
