Josiah's progress is pretty much the same. Right now he is in a stage of saying "No" to us all the time. He's had many time outs of it too! It's frustrating because desire to go on the potty isn't there anymore. He still goes pee-pee on the potty, but usually puts up a fuss. I try not to make a big deal of it because I don't want him to hate the potty.
Right now the potty training is at a plateau. Hopefully it will progress soon and he'll be doing poo-poo on the potty. I can't believe how well he's done so far. Hopefully he'll start to enjoy it again.
