21 mth DS has only about 3 recognisable words

[Romilly70]

He can Say Dada; started saying that around 1 year.
He never says "mummy / mama"
He goes through phases where he learns the odd word eg, "wheel", says it for a while - for any object then stops.
Also "nom / num" for something tasty (foodwise)

Everything else is just pointing to it, fetching it, physically moving you to do what he wants and either crying or saying "Hmm" instead of speaking

The paediatrician has checked his hearing and is fine, she says he just doesn't feel like talking.

He jabbers away in his own language and is a good mimic in terms of if he (or I) does something wrong and eg spills something he'll go Aargh! or "tut" Oh Ga! (God).

I would say he is very physical and advanced in his motor skillss, so his brain is probably concentrating more on that.

Just want to know why and what i can do to improve his speech?

Background we live in France. DP & I are both British, speak english at home, DS just watches in the night garden, so minimal tv and only since about a month. He probably hears french a 2/3 times a week, so doesn't really understand it, although can understand everything i say in english.

I think also because he is with me all the time, and i anticipate what he needs, he doesn't bother talking. He isn't at nursery yet - trying to get a place; hopefully from September, otherwise i will consider sending him to a childminder a couple of mornings a week, to socialize and improve his french.

I do read to him and ask him questions eg "where's the cat?" he points, we do counting (usually stairs) and he sort of counts too... also try and give him a bit of commentary when i cooking - he always pulls up a chair to stand on and look.

Am i worrying about nothing or is there anything else i can do to encourage him to speak?

Ooh, that's me!!

I still stand by what I said above.
My kids were all late talkers & they are mostly adults now... one of them is droning on about bench pressing & gorilla strength now. It all worked out ok.
