What did you transition your babies to when they - hopefullly - outgrew diapers?
What kind of training pants did you use? Did you still have them wear the plastic/vinyl coverings over them when they were in the toilet training phase?
How did you toilet train them?
I do know that sometimes people are incontinent for life - for whatever reason. So - if your children were in that category - I hope you found something that kept their skin in good condition.
