K.D.
I was always told to go by the rule of if they routinely wake up dry in the morning then they are ready. Haylee was potty trained completely at 20 months, and only had one accident (at school) in all that time. (She is 4 now) so let her go without, but explain to her that if she wets the bed she will have to wear a pull up for a little bit longer AND help mommy with the laundry that day. :)
