... you check that other dc have sun tan lotion on/aren't burning?
DD went to a friend's pool party on Sat. I gave her water-resistant factor 40 sun lotion. She came back burned - face, back, shoulders (despite applying and reapplying lotion), and thirsty - she only had 3 small glasses of water in 5 hours, and she hadn't been to the loo (didn't like to ask).
DD is 12. I know she bears responsibility for her own sun lotion, but if you were the mum, wouldn't you have checked that dc weren't burning? It was the first really hot day of the year! She has never been sunburned before... All the other dc at the party are burned too.
