We just started with my 21 month old DD a couple weeks ago. She's had a potty for a while. During the day she's in undies and we ask her if she has to go potty every hour or so. She'll also tell us. Most days she has 1, maybe 2 accidents. They usually happen when she's busy playing and I'm doing something like cooking dinner.
She hasn't pooped in a diaper in a couple months which is the best. No spraying! I wouldn't consider her fully trained yet, at all. But we're making progress. Still in a diaper for naps, nighttime, and the carseat.
Single mama to my sweet D. Taking life one day at a time.
