DS is battling some pretty bad diaper rash for the first time. Apparently he had diarrhea in his sleep a few nights ago and has kept having it and I can't get rid of it! Poor guy. We are using some desitin we got as a gift but it isn't helping. Is there an actual difference between brands? The ingredients seem the same bit everyone has a brand they swear by. Just wondering before I run to target to pick something else up! Thx!
