That said, I think there are definitely benefits to doing it when she's this age. For one thing, it isn't a fight. She's not old enough to realize she could refuse to go in the potty. She hasn't reached the stage of freaking out about trying new things. (At least, I hear that's a stage. Maybe some kids are just less likely to freak out?) And one of the biggest benefits (in my opinion) is that when she gets more verbal, and can work the pants/underwear on her own? She'll already be trained! I am very much looking forward to that day.
P.S. I totally won the $100.
