Hi J....
Do it!! Yes, it's possible - my daughter was fully potty trained well before she was two years old - it was awesome! (and like your daughter, mine was also walking at nine months) No more diapers...what a dream. I have her in the Montessori school in Palm Harbor and her teacher suggested it first. Since she's my first child, I have no prior experience and the teacher gave me a book to read - http://www.diaperfreebefore3.com/ - and we picked a date and just quit the diapers cold turkey. I bought some thick Gerber panties and just explained how she can't get those wet. For the first two days, we'd put her on the potty every hour...by the third day she was telling us she had to pee. The fourth day was a number two! It was finished in less that 6 days. We kept her in a diaper overnight for a couple months just in case, but only needed it a couple times. The other Moms are right - you need a solid 4 or 5 days with help from everyone - I couldn't have done it without the teachers help. Check out the Montessori School on Nebraska - they are wonderful!
Best of luck,
D.
