Baby gets a rash from berries

My 10 month olds gets a bad diaper rash after eating baby food with strawberries or blueberries. She poops like 4 times a day and gets a nasty bad rash 😭 and medicine will only take it away. I even put diaper cream on her ever diaper change. Has anyone else’s baby dealt with this?!?! Do they grow out of it 😭😭
