D.S.
My daughter is 2 and is wearing panties thru the night. She can hold it thru the night most of the time but after a couple of middle of the night linen changings I start taking her to the potty before I go to bed. For example she goes to bed at 8 and I usually take her again around midnight right before I go to bed. She never even really wakes up. I sit her on the potty tell her to potty and then lay her back in the bed. Painless. Just a idea. Good luck.
