I don't know? Every now and then my little guy asks to sit on the potty. So far, he hasn't been very successful, but I'm holding on to hope! If he potty trained now it'd be considered 'early'. He isn't even 2 years old yet, but one of my girls was completely potty trained before she turned 2. Come on, people, this would give me only one baby in diapers! Hope with me!?
