Multiply your situation by two and we went through pretty much the same.
Only issue was when my wife was away, I'd be cleaning up after one and the other would wait until that exact moment to drop a duece.

Was crazy there for a week or so. Now, they are all good and my wallet is a little happier.

Potty & Boo Boo is heavily used vernacular In my household LOL *#kanyeshrug*
