Keep some benedryl with you at all times. I know on the bottle it says not to give it to children under six but it is a life saver, literally and most of the time, this is one of the first things that the ER would give them anyway. Ask your doctor how much you can give your little guy in case of an emergency. The sooner you can give them medicine the better and when it comes to sever allergies, the time it takes to get to the ER might be too long. My daughters are allergic to peanuts and the first time I gave my oldest a peanut butter sandwich her face swelled up like a ballon. It was very scary! The benedryl stopped the reaction almost immediately and we did not have to take her to the hospital, thank goodness. Oh, neither my husband or I have any food allergies either.
