Ready or Not?

Not sure if we are ready for it or not, but tonight the little monkey is wearing her ballet undies to bed.  In the past six months, we've had a few spells of several dry nights in a row and many wet ones.  She's asked about undies before, but we haven't really thought about it until now.  The last two nights were dry and we've talked about it and how if she can't tell she needs to go potty while she is sleeping, we can always go back to the "princess pants" (pull-ups).  Even the Pampers newsletter Mama gets indicated that kids sometimes still have accidents at this age, seeming to mean that most are not still wearing diapers/pull-ups.  Wish us luck.
