N.P.
according to a study done last year (or earlier this year I guess) there is no reason to keep a child from any foods except milk (not cooked into items, but drinking cow's milk) and honey (due to botulism). The milk proteins can't be processed until certain flora develop in the intestines, and studies of actual intestines of infants found that those aren't there in 99% of the kids until 11 mos 3 weeks old.
But for all other foods they have found that there is no evidence that delaying introduction of any other foods is beneficial. They don't see any less allergies or less severe allergies by delaying items. In fact they saw the opposite in that allergies were more severe in those that had been strictly avoiding them.
So, don't fret.
Now, personally I avoid oranges, pineapple and tomato sauces until they are about 15 mos because lots of kids get SEVERE diaper rashes from the acids in those foods.
