It's "Potty Time"

I am sure I am not alone in this...The past four days Z has been in the process of potty training! The 3rd attempt (and I must say, 3rd time is a charm)!! At first it was really tough, he was so defiant and did not want to be bothered with it all. Then we decided to set a timer for every 20-30 minutes so he would know (also to help Mommy remember). Each time the timer goes off he gets excited and shouts, "It's potty time." He is to the point that he no longer wants Mommy in there helping and says, "Go out, I do it myself." Of course A has to be in the middle of it all as well. She is now to the point that when she hears the timer she runs to the bathroom door. Quite a difference from our first two attempts. I know it takes some time and especially patience but so far so good:0)
