I feel horrible. I have damaged my child.
We went for a walk and to the playground yesterday. I had forgotten my sunscreen, but borrowed my friend's. I put it on maybe 5 minutes after we started walking, but we were at the playground for a long time. He hates getting stuff put on his face, so he struggled a lot and so I probably didn't get it on well, and then I never re-applied. It was a really sunny day.
It didn't really look bad last night, but when he woke up this morning--at 5:45 a.m.--he was batting at his ears like they were annoying him, and his cheeks were bright red. Let the permanent sun damage begin! It looks worse in person :-((
