DD1 is 4.3. She has always met her milestones at the late end of normal - sat at 8mo, never crawled, walked at 19 mo, talking was okay but never spectacular (barely draws breath now, of course). Her numbers and letters have only really clicked in the last 6 months, but she still can't recognise many double figure numbers and probably only knows half of the alphabet (mostly lower case). I was getting a bit worried about her lack of interest in drawing and colouring, but she seems to have picked this up since just before Christmas.
Anyway, all of that is probably completely irrelevant, just setting the scene...
She has oodles of games and jigsaws and we attempt them as often as I can bear 
, but her concentration span is atrocious. We have probably completed a game only a handful of times, and it involves much cajoling, encouraging and speedy playing. At the moment, in order to not make a huge issue about it, I tend to say 'Okay, shall we just put it away now?' and clear it all away when she starts rolling about/hiding the playing pieces/fidgeting with other toys/bothering her sister etc.
At the moment I am just assuming that she just has a very short concentration span and ZERO interest in playing games. Fair enough. Or perhaps, she'll just come on in her own sweet time, as with everything else.
But. I have to say that I am concerned about her complete inability to do jigsaws. Even sorting out straight edges seems to be a mammoth task. I can do a whole jigsaw and leave one single (obvious) piece to fit and she will still put it in upside down. Could she have some cognitive development issues? Is that even the correct term? Should I be worried about the jigsaws and attention span?
Anyone have any pearls of wisdom?
