Potty training is one of those things that once you go through it, it’s like it never happened. My daughter and son have been out of diapers for 4 and 2 years respectively, but I can barely remember the kids ever wearing them.

So it was fun for me to work on a quiz for Parents.com about this very subject matter. It’s called What’s Your Potty Training I.Q.? and it actually brought back some memories.

Whether you’re in the dirty diaper trenches or you haven’t changed one in years, take the quiz and see how much you really know about this major milestone.
