Because ds1 can't concentrate for toffee. He was 3 two weeks ago.
Until now I've been putting it down to being an active, energetic boy, but I've noticed his friends will sit and do a jigsaw etc. I could get ds to do that with continuous one to one talking, but even then I couldn't be sure he wouldn't run off to play. Other children will sit and colour too - not a chance ds will do that for more than a minute or two. Getting him to stick some snowflakes on Christmas cards today was painful - I had to bribe him with virtually every one!
He will sit through a few books actually, but that's about it.
Other experiences please? What will your 3 year old do?
