I'm not sure where to post this, so I'm trying here.
We moved to from our townhouse to a rented house in a new town a month ago, and ever since my son has been breaking out in hives about 4 nights every week. It only happens after he spends extended periods in his bedroom. There is nothing there he hasn't had in his previous room. I did not switch detergents, he has hardwood floors (no rugs) and painted walls. I'm at my wit's end! What could be causing these nighttime hives?
