What I've learned about potty training
To clean up little puddles on the carpet or upholstery, blot up as much as possible with a rag. Sprinkle with cornstarch and a little baking soda and allow to soak up the extra moisture for about fifteen minutes. Vacuum. If it still smells the next day, break out the carpet cleaner.
To clean poopy clothes, put on your rubber gloves and swish around in toilet until you get rid of as much poop as possible. Then launder in hot water (with a tiny bit of bleach, if you like).
Keep disinfectant wipes at the ready for quick bathroom wipe-ups.
Don't ask me how I know; I'm not sure I want to talk about it yet.
