Have you left them with a sitter/grandparent/friend for a weekend away? How did your sitter and LO do?

LO 3 STTN maybe 1-2 a week and is all over the place the rest of the time. We are planning on leaving all 3 kids with my parents next month for a 2-3 night getaway. My mom says she won't mind the wakeups but i am afraid it will be too much to ask from her. I am thinking about taking the baby with us or just cancelling the getaway part of our trip.
