I think my son is doing fine. Seems to understand stuff - no, come here, get your ball/cart/teddy -has a few words etc etc and generally has no problem making himself understood non-verbally. But he seems completely disinterested in knowing his body parts.
We got a book, we sing to him, but he's always far more interested in just rushing off to the next thing to explore. Once or twice he pointed at his head or nose but now it seems random.
I don't think he's the fastest developer but neither the slowest - my SIL however (hothouser alert) is quite appalled. She thinks he should know...
Hence the concern.
Any thoughts or tips appreciated.
