Silly question here from a first time mom, but does anyone see any problems with using butt paste on my LO's neck? She is 10 weeks old and FF and seems to have done a good job at hiding some tasty milk bits in her chubby neck folds. We've been really trying to clean this area well at bathtime and after feedings but yet I will go back an hour later and find gross cheese curds in her folds. This moisture has seemed to cause a red irritation almost like chaffing or diaper rash. So, it seems like butt paste would be a natural way to help soothe the area. Does anyone else use butt paste here? Any other suggestions? It doesn't seem to be bothering her but looks quite red and I don't want it to become painful.
