A few weeks ago Meira (14 months) had a horrible diaper rash. It was her first serious diaper rash. (And also the first time that I was truly convinced that breast is really best -- I don't think it's a coincidence that she got her first diaper rash only after I weaned her. And Hila, who was formula fed pretty much from day 1, had chronic diaper rash.)
Anyways, it was really bad and I wanted to give her tush as much air as possible. So I took off her diaper and pulled out our little potty...just in case. At one point, I saw her squat and start to grimace, so I quickly picked her up and stuck her on the potty. She peed and pooped.
Later that day, while diapered, she made those same gestures, so I quickly took off her diaper and put her on the potty...and she pooped again!
Two weeks later and Meira probably pees and poops in the potty and/or toilet (with kid seat) 2-4 times a day. She still poops in her diaper sometimes (this is a kid who poops many, many times a day) and often pees on the floor, but we're having some fun with this pottying. Meira will sometimes run to the potty herself and indicate that she wants her diaper off (and always goes after that), or I'll pick up on her cues and initiate the pottying. Either way, Meira gets very, very excited and is clearly very proud of herself.
Now we just need to get daddy on board...
