You are putting WAY too much stress on how your 3 year old looks. She is young, not a care in the world, doesn't realize yet that when she grows people will so harshly judge on how she looks. This is what you want to teach her now? Come on. She's a kid. Let her be one and let it go. Use this to teach her a GOOD lesson, on how no matter what she is adorable and lovely. It's a much better, healthy, and valuable lesson then, "I don't want this to be all that people remember when they see her, I want her to be adorably cute again!"
P.S.
I NEVER said you were a bad parent. I don't think that, I don't even know you. I simply said if YOU focus on it too much, SHE will focus on it too much. That hardly equals a bad parent and I never eluded to that. You took that away from what I said, but I never said that.
