You're going to have to play detective and try to find out why. Big changes, fears, jealous of a new sibling or cousin, etc. Once you figure out why she's started this, you can work on solving the problem. Good luck.

Does the "school" require her to not wear diapers? There is no academic advantage of sending a 3 year old to "school." There are lots of reasons not to send her to "school." Many kids arent' ready for group learning experiences until they are 7-12. That's why in some states kids don't have to go to school until they are 7. Keep her home with you and save your money.
