I know your original message is from over a month and a half ago, but my DS will be 17 months old in a bout 2 weeks, and we've just introduced the potty, too. I have had it sitting in the closet, and thought it was too early to pull it out, in fact I'd read all the old stories about how introducing it too early can be harmful, especially with boys, but DS started giving me the telltale signs he was ready. And I truly feel, above all else, there is really no "set" age to have things started, or done by. Every child is different, and their readiness will pretty be apparent to you. For us, it was that DS would tug on the crotch of his pants, and look uncomfortable. He also has started bringing me a diaper or the box of wipes, when he wants to be changed. To me, that means he's aware of when he's pottied, the first step in potty training. After only 2 weeks, if I see him doing the crotch tugging, I ask, "Do you have to potty?" And he immediately runs for the bathroom. No overwhelming success actually making it there in time, but we're taking it slow, and thrilled wth small victories. This is my frst child (we have another on the way) so it's my first adventure in potty training, and I really have no advice for you, except that nobody speaks your child's language like you do, and if he tells you at 17 months that he is ready (or not ready) you should listen and take cues from him. Good luck! I'll be lurking to see what other bits of advice experienced moms give you, since we're right about where you are!
