I don’t have an issue if you need them the night before, but then the sit starts the night before. And you have a place for them to stay. I applied for a sit recently, in a one bedroom apt in LA. He had to leave at 4 am, and wanted me to arrive at 3 am. He was looking for a sitter that could come at 3 am. Even when I declined and withdrew, he messaged me and asked again. Now 3 am is unusual. But 7 am is more than common.
