When I was trying to get the kids to take a nap, I locked the bathroom door. I locked it because they already had several chances to 'go', and they kept going in there and playing.
After Michael and Emma woke up, Emma was crying at the bathroom door, wanting to be let in.
Michael said with a shrug,"I already went potty."
M: "It's okay. I went in the backyard."
J: "What?! You went in the backyard?! Where?"
M: "In the rocks. It's okay, Mom."
