LO has been eating a lot of berries lately (all different kinds) and I noticed this week he's starting to get a diaper rash. Not terrible but definitely some red bumps/irritation. Should I be concerned that he has some kind of sensitivity to one (or all) of the berries, or can that just be a normal side effect of berries? I'm thinking they are probably pretty acidic. He had a complete allergy panel last year and didn't show any kind of allergy, at least not to strawberries. I'm not sure if they tested any other berries.

Anyone else's LO get a diaper rash after eating berries or other fruits?
