Dry Underwear

The Tumbleweed has had two days in a row of success in underwear. Yesterday morning she woke up, took off her diaper, put on underwear and has been using the potty ever since. Today she even went to school in underwear. All in all she has done really well. A few small accidents, but nothing major. I was pleased with myself for staying calm and not overreacting to the accidents. She is still using a pull-up at night, but today she napped without one! She has been very excited to tell people about her success. Could this be the end of diapers?
