She is 3.5 and all week I've been applying the medicine but it isn't going away and the wedding is tomorrow!

Would it be bad if I put a very tiny bit of concealer on it just for the wedding? I don't want her to be self-conscious about it if someone says something to her about it (kids can be mean) I've never ever put make up on my daughter, Infact she won't be aloud to wear daily make up at all until she is an adult and chooses to wear it, but anyways there will be many pictures taken of her as she is in the wedding party and I don't want her to look at them when she is older and say, "mom why didn't you cover those?"

I'm really torn on what to do.
