He has 2 big brothers and between them they have so many toys.
Loads of Lego, playmobil, Hexbugs, Scalextric, dressing up stuff, puppets already. Got him a Hot Wheels set last year and it was a bit of a flop. So feeling the pressure!
He doesn't need a bike or scooter.
We usually do one "main" present plus a stocking. It doesn't need to be expensive (he has no idea!) as long as it looks reasonably impressive!
