Q: What is a good link to see the commercial for potty training with an upside-down book?

A: I think I see your problem right there.

The first lesson of potty training is to let gravity do all the work.

Having your boy stand on his head while using the toilet creates more work than necessary.

I guess it might make everything cleaner, in theory.

In practice, however, your boy has a whole lot of poop on his head.
