That's interesting AJP - I don't have the ABA book but my encyclopaedia on infant nutrition says similar - I'm hoping it's the case, DH was fully BF so no dairy till older but a lot of the later research into allergies by immunologists has been suggesting what you mention - but researchers and officials seem to change their mind every decade or so anyway just to confuse all of us. As a side point if kids or adults are just lactose intolerant as opposed to a full-on allergy than cheese is fine too (hard cheese contains almost no lactose interestingly) and yoghurt's good bacteria help to digest the lactose already. Now I'm hungry for cheese and yoghurt - ah to be a baby and not have to diet - I swear I am jealous of DD's food sometimes Congrats Heaven on 6 months breastfeeding and reaching solids age too, I'll get you in this thread instead (lazy I know)
