it's awful isn't it. The main things that come to mind for me when the boys have had bums like that is... either bit of tummy upset, cold (all the mucous) or antibiotics. Elijah's been on ab's last week and had a pretty sore little bottom a few times... I was told by my doc when Oskar had it from ab's once to use some Dermaid (the really mild one... .5%) just once or twice in the day... I used it one night and the next morning it was still red but when you touched it it was DRY and not all angry red. I have been using it on Elijah at night and sometimes once earlier in the day if need be and I think it's kept it a lot better than would've or could've been. In between that I use Amolin.

and hope it gets better fast!
