Battling Diaper Rash

Ugh. A diaper rash showed up Friday night. Got worse Saturday, and even worse Sunday - almost to the point of bleeding. Poor thing. We've tried Desitin, A+D Ointment, a light application of cortisone cream and even air drying but nothing seems to want to work. Nana recommended we try corn starch and nothing else. We tried it last night and it actually looked a little bit better this morning. Keep your fingers crossed.
