LO is 14 months old and we've not spent a night away from him yet, but we're leaving him with MIL overnight on Saturday night so we can celebrate our anniversary. Well, my MIL decided to stay with my BIL/SIL and their boys, so there will be a lot of people there (including ones who are more used to waking up with LOs in the middle of the night...)
I'm a little nervous about it but I trust them. It took this long for me to even consider letting him stay with someone else overnight!
How old was your LO when you first left them overnight? Did you leave them with family or a sitter?
