Ds is 2.3 now and will be 2.7 at Xmas. I've been looking at playmobil for him and getting all excited :) but what's the difference between playmobil and playmobil 123? I think he'd get more use out of normal playmobil but it says it's meant for 4+. would it be ok for him? He's quite 'grown up' and doesn't out things in his mouth etc
