"Potty" in the basement

I think Violet likes the potty more than Ava. This could be a problem. For all you germ-a-phobs out there, don't worry, the potty still has never been used. My hopes were raised this morning when Ava screamed, "stinkies!" and laid down promptly to have me take her clothes and diaper off. But alas, the diaper was dry and nothing followed. She obviously can hold it pretty well.
