My DS (who, similarly, was cognitively advanced but not advanced wrt to fine motor skills) got and loved for his second birthday:
- a set of children's tuned handbells
- a wooden train set (ebay! this is a classic example of stuff best bought second hand, as it's expensive new but lasts for ever)
- a tricycle.
And books of course. I think my main recommendation would be the bells, if you think your nerves will stand it: they were a tremendous hit and are still used. Do get a set which are in tune and pleasant to listen to :-)
