I swear this girl 2 going on 12. On Monday she decided she was done with diapers. She has worn underwear since and has done beyond great. Pees and poos on potty. She has even stayed dry through naps. Haven't tried night time yet; she sleeps a good 12-13 hours so not sure if she could do that or not. She has peed on public toilets and acts like she has done this all her life. She is very serious about her underwear and being a "big girl". So strange to have a barely two year old potty trained...Boys were both 3. We'll see if she keeps it up, but I doubt we are going back to diapers now!
