Bad mummy moment warning ahead :

I never even checked whether I could or couldn't give the boys rice milk - both have been on it since they were just on 12 months (and lactose free formula after I finished BF). I think the issue is that it is not a "complete milk food for infants". But if you are not giving them lactose free milk (some bubs are alergic to the protein in milk) and don't want to give boys soy milk because of the oestrogen issues, then rice milk is the go. Really though, if a 12 month old is having a full, balanced diet, then calcium enriched rice milk should surely be ok.
