Was taking care of dishes yesterday after dinner. Rebecca and Lucy were playing well together for a little while, then I heard sounds of conflict. Rebecca was opening and closing a door and Lucy was getting quite upset. I told Rebecca to let Lucy in.
A couple minutes later Rebecca came up and said:
"Lucy's bum is all stinky and messy. I tried to wipe it but I couldn't do it."
Check the bathroom. As I suspected, there was a poopy toddler, poopy potty seat, poopy pull up in the bath tub, a couple of errant poops on the floor and a little other assorted mess.
Obviously I couldn't be angry, as Lucy was just trying to be independent and Rebecca was just trying to help, but I had to try to explain that Lucy needs the help of an adult if she's going to be using the potty.
