Peanut's peanut allergy

So I had the weirdest/craziest afternoon...

When Nolan woke up from his nap, it was time to eat lunch. Nolan got a peanut butter and jelly sandwich, apples and Gatorade. He took one bite of the sandwich and spit it out of his mouth and rubbed it across his face. I could tell that he didn't really want it so he got spaghettios instead. Once lunch was done, and I'd washed his face, he started to get a rash around his mouth and nose. After about 5 minutes, the rash started to develop small white dots. It kind of freaked me out so I called his pediatrician, who told me to give him benadryl and come right down. So I gave Nolan his medicine and took off in the car. By the time we got there, it had been about 20 minutes since the benadryl was given, so the rash didn't look quite as bad. When the doctor looked at it, he said that Nolan probably had an allergic reaction to the peanut butter, which is really weird since I have given it to him before without any problems. He told me to hold off on the peanut butter until he was about 18 months and then to try again with a small sample of it. He also said that the allergic reaction was really different than the ones that they usually see. Nolan had no problem breathing and wasn't acting any different than before- he just had a rash.

So I just wanted to let anyone who might be in contact with him or see him in the next six months to know that Nolan can't have any peanut butter. Weird huh?
