I don't care what method parents use at home and I will work with them to be consistent, but not if it is a method that is totally not feasable in the daycare setting. I had a family when i first started doing daycare who trained using a method similar to the one above and, being inexperienced, I let them bring her to daycare in underwear because they said she was trained. it was a mess! I can't tell you how many times I had to clean carpets, change poopy underwear etc. And the worst thing is the child started resisting and throwing huge fits, refusing to sit on the toilet. I let it go on way longer than I should have. Now, the child stays in pull-ups or training pants (waterproof) until I am sure they are trained. Each child and family is different and can use whatever method works, but there are some things I cannot do in daycare like letting the child go bare bottomed or leaving a potty in the playroom for them to use, etc. Let them try their 40 page method and see if it works...if so then you can tell them what you are willing to do to support it at daycare and what you cannot do.
