Sit on it? Why? Oooohhhhh....
Most children in the world are never formally potty trained. They learn how and when to go naturally. I consider it potty learning and it begins at birth. I don't mean you stick your kid on a potty for hours on end, cajoling and bribing with cookie and Dora stickers. That doesn't work. Trust me, I tried. Think of it as a stage in physical development, like learning to walk. Your baby needs guidance and encouragement. Give it in spades. And teach by example. That's right, open up that door and let your kid go visit the loo with you.
And no, he didn't poop or pee in it.
Oh, and if you see Santa, tell him Gina needs a digi cam for Christmas so I can put really cool pics up instead of crappy camera phone pics. Thanks.
