K.D.
When we were potty training I found a product like serenity type things, but made for toddlers and children. I found it online. It was sized for little ones and made to handle all that they do! They worked great. Undies still had to be changed, but it wasn't an unbearable mess and usually clothes were still dry. I'm sorry I don't remember the name. I think it was Pods. I found them on a potty training website, but I can't find them right now. I'm horrible on the web! If you can find them it might be easier than having to retrain later since she just leaks a little. I hope you find a good solution, especially to the health issues.
