Wesley's outbreak of hives

Having to explain to Wesley why he has to stay home today rather then go to school. He has broken out in hives all over his body and can't stop itching!! He is so sad to miss school and the book fair. **If my parents said I didn't have to go to school I would be having a party!!

Today we will work on at home treatments and re-wash all his laundry in new detergent. Can't figure out what caused this!!
