DD is 3 and has been potty trained for a month or so now. She's fiercely independent and often goes potty by herself and often won't let us help. Last night in the bath I noticed her bottom and vagina are really red and sore. She cried saying it hurt when I asked to look at it. I'm assuming this is probably from not wiping properly. Or it could be irritation from the Kandoo wipes we have. Has anyone else experienced this? Should I put something on it? I was afraid to put diaper cream on it because it'd just get all over her undies.
