I have 2 19 month olds, my daughter and niece, and both have exhibited signs of potty readiness, but at this age there are some obstacles they can't really overcome, size being one, so I asked my pediatrician at the 18 month check-up and she said exposure at this age is great, letting them sit on the potty/toilet, but before the age of 2 it's more training you to get them on the potty than them actually mastering the skill. My niece will pee anytime you set her on the toilet, but doesn't understand not to do it in her pants. So I guess my response is that positive exposure at this age is great, but don't push it and don't make it a negative experience or it will prolong the process. As far as a paci goes I have found that most of the time if my daughter has hers and I ask her for it she'll gladly give it to me. We have a little plastic mug on her changing table with her name on it and that's where we keep them, in the morning and after nap she gives it to me and tells me "paci, cup" and we put it away. As far as naps/bedtime, you may want to wait until she's old enough to negotiate with, but that really depends on your determination to get rid of it. Are you willing to let her cry it out without it or is it not that bad. I have heard people poking holes in them so that they deflate when sucked on and some kids lose interest. Good luck with both!
