I wanted to wait until Eli was born to try and potty train Kate, so she was about 3 weeks away from her 3rd birthday when we put the diapers away and put on underwear! She has done really well! There was a day about 3 or 4 days into wearing underwear where she said to me with tears in her eyes, "I don't want to be big, I want to stay little." She wanted to go back to wearing diapers! I felt kind of sorry for her but after talking about it she decided she might enjoy underwear and now she says "Only babies like Eli wear diapers!" So now we only have one child who wears diapers and we are sooo glad! Hooray!
