When was the first time you spent the night apart from your child? Why? Who watched him/her, where, and for how long?

No baby yet, but just curious. Some of our family are already asking to have the new baby “sleep over,” and I don’t know how to respond to them. It’s not that we have any trips planned or any other reason we’d want someone else to watch him/her- they just want a weekend with the baby when it comes.
