Toilet Training Day ?

I lost count. I think it has been a little over a week. Every night before bath, we would sit Josh on the potty and encourage him to go. The first 4 nights, Josh peed and pooped in the potty. No fuss, no questions asked. He just sat down and did his business. I was delighted as I thought this was the next phase of my happy, easy, mellow baby doing something new. Wrong! After 4 nights in a row of success, we haven't seen another successful night. Many of the nights it is Joshua sitting there reading his Elmo Potty book and then getting up saying "all done" without doing anything. Other nights, it is Joshua saying he is all done and then peeing on the bathroom floor after getting up or even peeing in his diaper as I am taking it off to put him on the potty. Oh well. For now, we are going to continue the potty at bath time and as he does start to get the hang of it, we will add additional times during the day. We are in no hurry to toilet train Joshua and didn't expect to start him this early, but if this is what he wants to do, then we are more than happy to teach him.
