Americans start training much later than almost all other cultures and also make it into a much bigger deal than it needs to be. I also highly doubt that other cultures feel the need to spend a lot of money on special equipment to get the task done. After all, once upon a time it was accomplished with nothing more than a chamber pot and an outhouse. Children haven't gotten stupider since then, but their parents sure have. There are parents who will buy five different types of potty chairs thinking they have to experiment to find out which one each kid likes the best. Then they wonder why the kid is confused because they aren't doing something consistent from the start. Then there are the people who actually move on to hiring consultants. Somehow, they think if your aren't spending a lot of money on it, you're not doing it right when it is really the exact opposite. If you're too stupid to be able to potty train your kids without nothing more than a little advise from your pediatrician, then you probably shouldn't have had children to begin with. It is a natural process and shouldn't take anywhere near the time and financial investments Americans make to accomplish it. Their product will probably become a huge seller just because people are too stupid to realize they don't need to spend money on it. They already had Robert convinced he had to go out and buy two immediately for his kids.
