birthday present for poss g&t 4 year old

[barbapapa]

What do I buy for a little girl who may be g and t. She is not at school yet but reads and is very bright - may have been identified as g&T already I don't really talk about these things with her Mum. I know that hse does very complicated jigsaws and likes maths. Any ideas?

FWIw I had a very G+T ds and he got ordinary toys like lego/knex/meccano and loved them.
My dd is 4 and reads and her fave toy is this

time telling wall hanging

Bit pricey for a friends child though but that sort of thing is pretty cool.
