My daughter will be 4yr next month. She has been potty trained for 2yrs now. She wipes very well.....front to back (one swipe). I wipe her when she poops b/c her arms are not long enough to get it good. WELL.........the past week she has said off and on that her 'tooshy' hurts. I have just been brushing it off to her picking at it or just not wiping good. So, this morning she woke up and said it really hurt. I don't see anything different or out of the ordinary with her. She's prone to UTIs, but this isn't one. How do I know if she's got a yeast infection? Hubby says she needs to drink more water (which she does but won't). I'm very sensitive down there too. What should I look out for? THANKS!
