I wasn't worried about the gluten, just that rice constipates and the other two do not.
So strange that every country has such different recommendations with introducing solids! In the last year, Canada has removed all recommendations for restricting anything... Although, many doctors still support limiting things like berries, egg whites, and acidic foods like tomatoes, kiwi... I don't limit Alexandra really, but I do use common sense... she hasn't had anything like fresh berries, tomatoes or citrus simply because of the common reaction many kids have to berries and because of the acidity of the latter two...
