Hi! Well, I have no answer, but thank you for posting this..I have been meaning to do the same. My daughter, also 4, has a similar issue. She also seems obsessed with her vagina, and often after she goes to the bathroom, she insists that she has to look at her vagina, and it is a tiny bit red..but she seems to "need" to pick at it. We have 3 cats..and don't ask me how..but sometimes there is a piece of fur there. She also says that sometimes it hurts. I have mentioned this to our pediatrician, and he says to soak her in a baking soda bath...and I feel terrible to say I have not tried it yet. Anyway, I appreciate you posting this, and am looking forward, also, to any advice.
