Kim,
Ringworm, as you know, is highly contagious. Keep the babies isolated together in one room. If Rebecca is older, chances are she won't get it. Older cats immune systems have a way of fighting it off.
Go to the drugstore (ask the pharmacist which one is best) and get athelete's foot cream and apply it to them three times a day. Wear rubber gloves at all times and wash your hands (I'm sure you know this).
My RB baby Marina Mar (1999) had it on her ears. It took almost 3 months to finally clear up. My daughter and I took turns sleeping in the room with her so she wouldn't get lonely.
Please don't get down on yourself. Things like this happen. I know it seems hopeless at times, especially when you have so many cats. But you guys will be in my thoughts and prayers.
