This happened a couple of years ago. We are GenX. My daughter, who we had rather late in life, was having a birthday party with a couple kids - I think they were 9 or 10 yo. Several of the other kids moms were millennials.

The moms bring the kids over and we explain what we're doing and say the party will take maybe 3 hours.

But then the moms stay. We're sort of wondering whether they're going to leave or what. Nope. Apparently they're staying to, um, supervise their 9 year olds?

After a bit we head over to our small outboard for a cruise and some swimming. Keep in mind, the boat seats like 6 adults max. The moms come down to the boat. Sure maybe they want to ensure we have enough life jackets and it's all safe. But then they jump in the boat and oh it's crowded! They're coming with in order to, I guess, lifeguard?

What is going on here? When my kids go to your kids birthday party, it's all you my friend. Let me know when it's planned to be over and someone will come get mine. Or maybe they'll have to walk home or get a ride with someone else or something.

This must be the helicopter parenting I've heard about!
