My dd 13 laid in the sun in a bikini at the weekend without suncream on. It wasn't warm, so she didn't think she'd burn and I was out so unable to educate her. She burnt her front quite a lot and is in pain. We've cooled it, kept fluids up and used aloe vera gel and it's calming. She's getting in a state about going to school today. She was off yesterday and I feel it is unreasonable to have 2 days off when it was self inflicted. WWYD?
