The first day, she managed to hold it all day long. At bedtime I put a diaper on her and she then peed and pooped.
Okay, this really made me laugh.

Although the UTI - not so funny. But I can relate with the stubborn, strong willed DD who knows the drill and rejects it.
Just today, however, DD 28 mos.'s new preschool started working on her potty skills. So I'm getting expert help from her preschool teacher with 20 years of preschool experience and 5 students age 3-4 who are potty trained. Good luck to them all.

At home, DD has potty trained herself quite well: Nature Girl disrobes and goes in the garden. I scoop hers along with the dog's. Hey, I'll take it.
