We've had the potties for a while now. For the past 5 months or so the girls will go in to the bathroom, and sit on the potty. It's a very rare occurrence in my house of going to the bathroom alone :-). They come in, we take the diaper off, they sit on the potty, they usually fight with each other (that's what I get for doing them both at the same time), then they ask for "paper", and then they flush the big toilet. This has been going on for a few months...we have the process down, but nothing has made it's way into the potty.
The school has "officially" started to potty train them. They sit on the potty several times a day, but as of today, no go...literally :-)
I've come up with a cute little song. They girls seemed to be musically inclined and we have songs for everything. This will be a number one hit one day, "We go peepee in the potty, we go poopoo in the potty." That's it, very complicated I know. The girls like it and dance to it so we will see. So here's on to another adventure in twinland :-)
