Ds, 3.4, has a box of Duplo type bricks and doesn't do much with them, so I'd like to get him a set to see if this encourages him to play. He does Small world play at nursery apparently like all the other things only seen at nursery but not so much at home. He tends towards toys aimed at younger children, though has never taken to happyland.
So which would be better for him? Duplo, for example the number train or my first fire station, or lego juniors - about which I know nothing. Help!
