Anyone with babies who had a reaction to berries?

I'm just wondering if they eventually grow out of it? My son loves blueberries & raspberries (he is only about to be 10 months on the 15th) but they give him a horrible butt rash. That's the only reaction he has, though..nothing scary. I'm just looking for hope that maybe one day he can eat them again.
