Sleepover with "new" friend

[chipscheesentomatosauce]

DS(12) has been to lots of sleepovers over the years, all with kids from his class in primary, or my friends kids, or the childminders son, but all those whose parents I've "known" to some degree or another.

He's now been invited to stay with a friend he's made in high school, whose name he mentions a lot, but I've never met him or his parents.

The other boy is going to give his mums number to DS to give to me, so we can arrange, and DS will have his phone with him, but it still feels like a big deal letting him go stay, what is to me, a strangers house.

What do others do here? On the one hand, I don't want to baby him, I know this is him making new friends and I'm really pleased, but this is the kind of thing that would have been made a big deal of when I was a kid (but my family set up wasn't really the norm).

Thanks.

I think this is a normal part of moving to high school, isn't it?
