I know Carlyn is only just about 15months, but for the past month or so, she has been telling us when she needs to poop! So, we bought a potty...an elmo potty...just to see what she would do. For the past couple of weeks, we have been putting her on it when she tells us she needs to go. She sits for a while, asks to get down, and if I entertain or distract her, she will stay up there...and the other day...she went pee-pee on the potty!!! YEAH!!! She has gone two or three times. I hope this continues, but am not going to push her since she is still so young! However, I was potty trained at 16months, so we'll see! Any suggesstions from you expert moms out there???
