When Maddie turned 18 months old last month, I purchased her a potty seat to fit on top of the regular toilet. We decided to forgo the little potty and see how Maddie would do with a small toilet seat instead.
We've been very casual about it and we're in no rush whatsoever. But, Maddie likes the potty and "asks" to sit on her little seat 2-3 times a day.
Today, she actually peed in the toilet for the first time. She also grabbed a few squares of toilet paper and wiped herself (sorry, TMI but I'm so proud!).
Even though this is only the beginning of potty training, I think we're off to a good start.
