Hi D.,
I dove in early for this DREADED Task, it was no picnic. My daughter started potty training at 18 months. She is now 20 months and most days stays completely dry. We used the book "On Becoming Potty Wise". It was VERY helpful, at such a young age she does not consistently tell me when she has to use the potty (except at naptime if she does not want to sleep) However, as her bladder got stronger and I saw she could Hold it longer I decided to just put her on the potty every hour.
Even if she protests. 9 times out of 10 she WILL protest b/c she does NOT want to stop playing. So I think someone else mentioned the importance of a routine and here is mine:
I Try to put her on the pot every hour or so (if at home) If we are about to run errands she must use the potty before we go and as soon as we get back home, I put her on the potty as well.
Thus far this strategy has worked EXCELLENT! She stays dry most days and is even dry during most naps. She may have an accident once a week and usually it is b/c I got caught up in doing something and forgot to put her on the potty.
I used treats in the beginning Lots of Chocolates, stickers, cookies etc. But now we only use praise and we not only praise her when she uses the pot BUT we also praise her when she is DRY. We try to do period "dry" checks and say "Good Job staying CLean & Dry" because ultimately this is the goal. Hang in there, I hope things get better!
PS.
For my own sanity, I do have her wear pull-ups when we run errands, and during naps. I DO Not treat it like a diaper and I call them big girl panties. So if we are shopping for a long time (over 2 hours) we just use the potty at the store. I keep my potty top with me, b/c it fits right in my diaper bag and on any adult toilet seat.
