I've been thinking about this 4 Noah.

We would like to get him a trainset with one of those tables you get for them to go on.

Some kids cooking stuff i.e apron, bowl, spoon, cookie cutters etc
swing set or outside play equip
another thing I'm going to make soon is get some cheap wood and Phil will get a jigsaw from work I'll draw on different shapes (big ones) like a car etc then cut them out, paint them with blackboard paint (u can buy small tins at spotlight for about $13) and attach them to the fence outside to play with
Paints for finger painting etc
