My daughter seems not love sleepovers as much nowadays but she had a sleepover party for her 10th and 11th and I just put out piles of snacks and told them to turn off the light at midnight. No idea who was wearing what at any point and wouldn't have thought to check. Pretty sure no one brushed their teeth. I did find out I need to be slightly more mindful on the snacks as one of her friends couldn't self regulate and ended up eating enough junk to make herself sick so the next year I put out tons but had them all make snack boxes for themselves and put the rest away.
Of course if anyone needed medicine or had any particular requirements I'd check on that though! My daughter has a daily inhaler and I'd expect her friend's parents to double check that she had it for everyone's sake but I usually text her to remind her anyway.
I am the hoster of my many sleepovers and have sent my kids on plenty, including my ADHD kid. My expectation is that kids are safe and having fun. Full stop. I reminded them when they were younger to put on pjs and brush teeth, but if they didn't, oh well. I would have asked the parent to give the meds if it was important -- my DD would have never remembered that (because ADHD...)
"Hello babies. Welcome to Earth. It's hot in the summer and cold in the winter. It's round and wet and crowded. On the outside, babies, you've got a hundred years here. There's only one rule that I know of, babies-"God damn it, you've got to be kind.”
My dd is having a sleepover tonight and my extent of parenting was feeding them and blowing up an air mattress. I got them some extra blankets and checked in before I went up to bed. There are four of them here for their bday and while they are now 14- this has been my involvement for several years. They did get covered in mud while playing hide and seek outside so I’m washing sneakers too.
