My three and a half year old has been wearing underwear for a year. But relieving herself in the toilet was only one step of potty-training. There are about 40 other steps that are conveniently skipped over in parenting books. The "transition from little potty chair to big potty" step. The "yes, you must flush every time you go potty" step. The "weening from potty-rewards step" (otherwise known as, "no, grown-ups don't get M&Ms for pooping" step.) The "privacy without locking yourself in the bathroom" step. The "not everyone wants to see your new Hello Kitty underwear" step. The "not discussing what mommy is doing in the toilet in public bathrooms" step.
