My dd6 got a rope burn on her pelvis area from her new life jacket strap ( the one that goes through your legs) She complained about it yesterday and it was just reddish, so we made her stop using the life jacket and it went away. This morning it is a big scab. I put antiseptic cream on it but she says it still hurts and that her underwear is rubbing it. Should I just let it air out or should be cover with a band aid? If we did didn't have a family reunion ( and we are the ones bringing the tables and tent) i would stay home and let her go "commando" but that isn't an option
