I've been allergic to strawberries since I was 7, my two older children don't seem to be so I've been buying them this season. My youngest had a bit too many yesterday because her sister gave them to her without me in the room (5-6 of them), she was fine yesterday. Today I gave her a peanut and jelly sandwich and 2 large strawberries for lunch. About 2 hours later she threw up only fruit, 4 times then fell asleep. The episode lasted for 30 minutes maybe. She's still sleeping 1.5 hours later, a normal nap lasts 3.
Have you had any experience with allergies that cause vomiting? I didn't notice a rash, no fever, she's lethargic though, but she also skipped her nap.
Just before the episode she and her sister were jumping around tickling and chasing each other, not really sure that that matters.
I'm trying to rule out another stomach bug!
