DS knows loads of individual words, I couldn't count them, he basically knows the words for most things, and says them, but his speech is not very clearly articulated at all and to me his speech seems behind his peers at nursery, he sounds quite babyish iyswim.
So for example I can understand what he says but sometimes DH won't hear what he is saying as he spends less times with him than I do.
In nursery we had the problem that they weren't aware that he knew colours, could count and recognise some numbers and letters etc because he hardly ever talks there. He's now been moved up with the next age group and seems a lot happier, but still isn't talking to anyone.
How do you know what is normal or not? DH had speech problems as a child and I wonder if DS is the same. I talk to him a lot, we read to him and do singing etc.
