Hi! This is my daughter, Lilly. She seems to be having an allergic reaction to something. She hasn't eaten anything She hasn't had. I used a different laundry detergent than we normally use, so I was thinking that is what's going on. She came home from staying at grandma's house SUPPER fussy. I figured she was tired and gave her a long nap. When she awoke she was still extremely fussy and had a slight rash. She was up all night screaming. The doctor this morning told me to give her children's benadryl. (Gave 20 minutes ago) This is our first time with a reaction like this. Does anyone have any advise on how to help sooth her when she wakes up? It's gotten better since last night. This pic was taken early this morning of 7/10.
