In the past she's shown some interest in it but she would do well and then begin resisting. I have no interest in pushing her so we let her lead the way.
Today at 2:10 today she found a pair of big girl underwear and asked to wear them. I figured what the heck, I was expecting maybe 10-15minutes of dryness from her but I let her try anyway. So we sat her on the potty, she didn't go, but she got the underwear.
She surprised me that one. She remained dry and at about 3:30, 4:30, and 5:30 she peed on the potty. At 5:50 I sat her one last time before putting a diaper on her for bed.
She did so well today.
I'll offer her underwear tomorrow but if she does diapers oh well, at least I can see she understands whats going on.
If she does keep it up I'll be extremely surprised and happy. Also there's not much cuter than a chubby little toddler in underwear!
