DS2 is 22 months and has about half a dozen words - yes, no, up, down, ta, mumum, dadad. He doesn't use these much, unless prompted - just goes 'UH' and points a lot to get what he wants.
I haven't really been concerned about it but was just watching a video of DS1 at the same age and he was talking in sentences! DH feels we should maybe approach the HV about it, I'm not sure if it's too soon to drag in the professionals? He points, follows instructions, interacts socially and understands everything you say.
Experiences appreciated...
