My one year old was given a peanut butter cracker today. We have not given him peanut butter yet, primarily out of fear. He had a reaction of some sort. His little face got beat red and looked almost like hives. We got him to the ER where he was given an antihistamine. We were told it could have been a reaction to peanuts. No one really verified. Does this sound like it could be a reaction? The redness started to fade prior to being given the medicine. It is all gone now.
