M.B.
Interrupted sleep is better than none (most times) but still isn't great. I read somewhere that a parent fastened a ribbon across their child's doorway at chest height. When she ran into it, it was a reminder to go back to bed. You could try that with her maybe so then she only comes to get you when you she has to go potty. Just a gentle reminder to get back in bed. Practice during the day and cross your fingers at night!
