So Xalya is 7 months old, about 9pm we tried a new food which was Pineapple i let her suck on and then mashed a couple bites down for her to eat. I just changed her and noticed this rash on her stomach. She hasnt had no other new foods, but almost 8 hours later and just now a reaction? Does it look like an allergic Reaction to the pineapple and is it evem possible to have a delayed reaction????
