wake her up?

doggie mama

I have to leave at 6:15 two mornings a week to take DD to my MIL's. She usually wakes at about 5:30, although she has slept later a couple times. This does not give me enough time to feed her and get her back to sleep. Yesterday I had to cut her feeding short, and she never did fall back asleep. So, should I wake her to eat earler, like 4:30 and hope she goes back down? I could pump in the car I guess, but I'd rather nurse for some relief. I could pump before she wakes, but then what if she wakes up during and besides I'd prefer to keep my punp packed and ready to go.
