I think mine comes from Alyson's hand prints.
I don't know about this little-girl thing. 18 months ago I came home to a quiet, event-free home. Yesterday I came home to a mother that proudly went into the bathroom pointed to Alyson's tiny potty and said...and I quote....
"Move the paper aside"...
Now friends if you told me 18 months ago I would have put my finger in a toilet and pushed aside some toilet paper to see the "surprise" that Alyson left, and been so happy about it,I would have never believed you. But I was. I had to for Alyson as positive reinforcement is the only way to potty-train a little girl. Funny how this being-a-daddy thing changes you...
