M just used his potty chair for the very first time. We were lying in bed and he said "want to sit in potty chair." I said, "Ok but you have to take off your diaper to do that." He said ok and took off his diaper. When I took him to the bathroom he didn't want to and peed in the hallway. I picked him up and sat him in the potty chair and just talked to him for a few minutes and then I heard his potty chair make the little song and heard a trickle. Hooray!! I was so proud of him! Gettin so big on me already!
