Do you drop off at your sitter's house or do they come to you? Do they put the kids to bed or are the LOs asleep when they show up?

MIL prefers to watch the LOs at her house but she is coming over tonight. MIL wants LO2 to be asleep because she has TERRIBLE grandma anxiety right now and she wants LO 1 to stay up 30 mins later. I will honor her requests.
