This is one of those things where I can't work out if I'm being a paranoid mother of a PFB, or whether it really is a concern - please be gentle if I'm being silly! Today DH and I were having a conversation about how, while he seems to have met all his physical milestones so far on time, DS (v nearly 10 months) seems a little behind all the other babies we know with communication. We were just saying it in a kind of 'ah, guess he's more into moving' way, it wasn't a concern. But then DH mentioned that DS does wave and clap - but I realised that I don't think he has in weeks, and when I asked DH he hadn't seen him do it either. I've tried on and off this evening to get him to wave or clap with no response. Is this normal? Or should we be concerned that he seems to have lost these skills?
