Peanut Butter update

I wanted to give all of you an update on Hayden's possible Peanut Butter allergy. As ya'll probably remember, last fall when visiting with a friend and her little girl, Hayden had some kind of reaction. His nose and eyes were very itchy with a runny nose. We gave him benedryl and he was fine. Our only thought was that the little girl Hayden was playing with had had some peanut butter earlier and was very lovey on Hayden. So from then on we have decided not to give him peanut butter for a while. Well today I thought we would try actually eating it. I gave him just a peanut butter (sandwich) cracker after he got up from his nap. I only gave him one so I didn't overdo the PB for the first time. Well he seemed fine and so we headed up to the YMCA so that I could workout. As we were walking on the sidewalk to go in, Hayden threw up very badly. It very much scared me because it was a lot and he hadn't done that before. Evidently someone saw us because I called inside (on my phone) to see if someone could come help me and one of the front desk persons was already walking outside with cleaning spray. (only to find out he needed a hose instead)
So I called the doctor. (I never actually got to go in the Y) She said that it could be a reaction to the peanut butter but not to worry yet. She said if he stayed sick throughout the night to then bring him in in the morning. (it was 4:30 at this time) She also said not to do PB again til a later date. (I'm hesitant on ever doing it) From that point on til about 1 hour later Hayden was sneezing constantly which seemed to also have been a reaction symptom. Without the sneezing my other thought was him throwing up could have been from the heat. I do need to mention this though. When we were walking up to the YMCA on the sidewalk (seconds before getting sick) Hayden was jumping over the cracks. (Suzie, you know what I'm talking about) So he was feeling fine. Then when we got home he was just himself. Jumping on me, eating, and playing! I say (type) all this because if you keep Hayden ever (mostly to the grandparents) keep Peanut Butter or nuts of any kind out of the menu (not that ya'll have put it in there but you know what I mean) and also to pray for our little guy; we hope it was just a little reaction and he is all better. Love you all!!! Hope to see you soon!
Love,
