She's toilet training (not litter, toilet) and just advanced to a new level. The couple of days around it are always iffy but she usually gets there in the end. She doesn't usually choose something that's hard to clean for a toilet, I'd just shut off her other choice & my back was turned.
I figured as much regarding the costumes. Probably best just to chuck them then, since they don't fit & were only going to be gifted to baby bellydancers in my class.
