B.S.
Every baby is different and there are books that contridict doctors so everyone has an opinion. If you have immediate family history of allergies definitely steer clear. My son (he's 2) loves pineapple, oranges, etc all the acidic fruits. However his bottom becomes inflammed as soon as he pees. I can't get the diaper off fast enough. So he gets a little in fruit cups but that's it until he's potty trained. He just can't tolerate the acid. So my advice is try things out slowly and if he likes it then great!
