I recently had some of my son's 14/15-year-old friends stay the night. Out of 7 of them, only two of the mums checked in with me that it was ok. I obviously had no issue with any of them staying, but I was surprised that the parents didn't message me, as I would want to know exactly where my child was (at 14, I was off clubbing in London doing all sorts, so I don't trust teens

).
If it were me, I would get the mum's number and ping her a little message, thanking her for having your daughter stay the night or something along those lines.
