Besides screens and Lego!
Thinking of toys, what does your ds play with? My ds has a few dinos and cars, which he digs out occasionally. But he mainly draws, writes, reads, Lego and minecraft.
It'd be nice to get him something to actually play with iyswim.... or am I just having to realise that they don't actually play with toys that much at this age? I'm sure I remember playing with toys at that age
