LMAO!!!
That is great!
Seriously, Neat, I work with kids, and as long as they learn before they leave home or get married, all is well. Not to upset you, but some kids are harder to train than others. The bottomless idea has worked for many, however it's best done when kids can spend the majority of their days outside and just run around in the buff with rubber boots on or something. Kids who tend to go hide in the corner and poop are statistically the toughest kids to train. It took my nephew until he was four, and he was one of those run and hide kids. Your son is quite young and has lots of time to learn (while you rack up the expenses in diapers). But if you persist, with lots of tangible rewards, he will learn eventually!
