N.B.
I totally agree 100% with the Fisher Price Froggy Potty. I do home daycare and generally hate these things. They are messy to clean and empty and I dislike them. But this one is fantastic as far as stand alone seats go!
I move kids to the big toilet ASAP, but this one makes kids sit sort of wide (they all want to "watch"), has the high front for boys...its great. And inexpensive...$10-$12 at Target or Walmart when I got mine!
Go shopping!!!
