What classic toys are there for boys of this age, that are likely to get play value? Playmobil? Lego? We have a few bits of 'normal' Lego but none of the kits - are they any good or are they a bit dull once you've built the model? (and are the kits too tricky for 4yo's to do by themselves anwyay?) Or I thought some car track stuff would go down well - the sort of thing where a car loops the loop around a track.. what are some good makes? Any sets where yo ucan add bits on would be great, as other family members will want to know what to buy him.
Garage? Castle with knights? Pirate ship (Playmobil one is fab)? Aeroplane (also a good Playmobil one)? Outdoor toy such as a trampoline? Scooter? Balance bike? Brio or equivalent railway track - with some Thomas engines?
