Charlie's cord fell off just before she was 1 week, now she is 4 weeks old. She had a diaper blowout that went up the front last week, so I cleaned her up and gave her a bath. Now the past couple days I noticed there's some crusty stuff inside and deeper inside is kind of red, not the outside though.

Is there something I should put on it, vaseline or neosporin? I don't think it warrants a trip to the dr just yet.
