I didn’t realize at the time that it was related to her wheat allergy, but Kaelyn would eat happily. Then she would typically fall asleep (the only time that she slept). About half an hour after eating, she’d wake up screaming bloody murder. She is an extreme case though.
When my girls get into food that they shouldn’t now, they get bad diaper rashes, dark circles around their eyes, red rings around their bottoms, weird rashes on their stomachs, arms, legs, or faces, and mucousy poops.
