I'm sure this topic crops up on this board periodically, but I just wanted to see if anyone can give me some reassurance - at least so that I can get my mother off my back if there really is not a problem.
My son is just over 20 months, and is yet to say anything even resembling a word. We get da da da da or a a a a and, honestly, that is all. He does babble with this one syllable animatedly at times and points to things, but has shown no interest copying words or noises (e.g. animal noises). I chat to him all the time, he goes to a wonderful nursery (where they have always commented that he is very very quiet) and his motoric skills are fine - he was walking at 12 months, is very athletic, climbs everywhere, feeds himself well etc, however he can't do things like sticking his tongue out, blowing a kiss or blowing through a straw/recorder. I don't think there's a problem with his hearing, I think he understands me ok but he just does not communicate anything back.
I guess I would love to hear if you have had similar experiences, when to intervene and what kind of help is available. Or whether I should just chill and wait 'til he is ready.
