I tried to get stickle bricks for G at Christmas but couldn't, will get some this year, they are fab.
A DS game might help her concentrate, didn't take long for G to get the hang of it, you just need to sit with them to encourage patience

electronics aren't all bad, depends what you choose.
What about a Dora laptop, they are good, Roller skates

some one gave G some for her 3rd Birthday!!!!! Does she have a dolls house?
