My 2 three y o's favourite thing to do during free play is to get all the toys and pile them up somewhere. E.g. put all the little people in the vehicles and bring them over to the table and set them up under it. Or put all the play food on the table or inside the playhouse. The play is just the collecting and placing of the toys in the desired location as once this is done they don't really do anything with them. They are happy so I usually let it be unless it causes a problem e.g the other kids don't have any vehicles or if they have trouble cleaning them up...any thoughts? It's funny to watch them.
