E decides that it's time to use the potty

I can't believe it!   Today E peed and pooped in his little potty!   He started the desire to go to the bathroom on our toilet.   But naturally our toilet seat is too big for E's little behind so we brought out his little toilet.  This morning he said to me "mommy, I have to go pee pee."  I said okay and he walked to the bathroom, pulled down his pants, took off his diaper and sat on the potty.   He proceeded to tell me to close the door.  About 2 minutes later I heard him say "pee pee" and I walk in the bathroom to see and low and behold there was pee.   I could contain my excitement that I screamed "Yay Evan!  I am SO proud of you!  You went pee pee on the potty!"  He jumped up and ran into my arms and squeezed me.   I kept telling him he is such a big boy and I am so happy for him.   He was so happy too!     Later this afternoon after we ran a few errands, E played for a few minutes and then told me that he had to go to the potty.   I told him to go and let me know if he needed any help.   Five minutes later I hear him say "poo poo mommy" and I walk into the bathroom doubting there would be any poop and sure enough, there it was sitting at the bottom of his little potty.   What a proud day!   Now to see if he can do it all day.  Now there's a challenge!!!
