Once you have the diaper rash healed (using triple paste and corn starch if it's really bad) Aquaphor is your next best friend. In addition to keeping the poo from hitting the skin, it also works on dry cheeks (the ones on his face). This stuff is great.
If your baby has eczema, or baby acne this is a MIRACLE cream! My baby had HORRIBLE baby acne and a little eczema and after trying everything in the books and doc visits I came across this online. The reviews are all so positive and thought id give it a try! Within 48 hours my poor baby's face was CLEAR!!! 100%!!!!!!
