Wiping off Contact Hives

I recently heard a great tip. When your child gets a hive from contact with an allergen, such a peanut butter, a milk spill, etc. If you first try to wipe it off with a regular old wet wipe it may disappear without Benadryl or Anti-Histamine. I tried it the other day when L got 2 little hives on his leg. It worked. MAGIC! I hope this trick will help when L and B get hives in the grocery store from touching so many things, despite my best efforts. Hope this tip works for you too!
