I thought I may get the answer in this section.
Ds is 20 months and doesn't really talk yet, has a few words/phrases. Lately he has been doing a funny thing with his hand, which to me looks like a sign. He holds his hand out in front of of him and moves it in a circle in the horizontal plane. He does this all the time, does anyone recognise it as a sign? I'm not sure if it's just a random thing, one of his favourite programs is something special, so it's possible he could have picked it up.
He mostly seems to do it when he is enjoying himself, or sees something he likes.
If not is this something to worry about? I'm trying hard to do the whole nonchalant "oh he'll talk when he's ready" thing, but failing miserably and contemplating talking to the Gp.
