I read the first part of the article too and got stuck on the bare bum for three months part...if I did not have a daycare, I would be fine with this and actually did this for about a week or two when my son was training...but, with the daycare, there is no way I am going to let my daughter or any other child go bare bum. My daughter is 20 months and has been obsessed with the potty for months and occasionally actually pees in it and usually wakes up dry (last night she slept with no diaper...I didn't realize she had stripped before going to sleep...and woke up dry), but I have been waiting until she has more success in the potty before trying underwear. We have some cloth training pants that are waterproof, so we'll use those when we get serious as my experience with the waffle undies is that they leak and I end up with pee on my carpet (two dck's have confirmed this for me so far).
