DS is 10, but manages games for much older children.
He loves building things. Lego is great, but we have too much Lego now and it's costly given he does the sets in a split second.
I've bought him a book nook in the past. That worked well.
Another hit gift was a bionic hand that he built.
Does anyone have any ideas that might challenge him and keep occupied for a while. I'm really struggling.
