More of a what would you do than aibu I suppose.
We live on the end of a quiet cul de sac, with a park & field at the end a few houses down. A lot of kids here 'play out' at the park, scooters, bikes down the road etc We've started letting ours (10 & 6) out to play with them, with strict rules and I keep an eye from the window.
However the last week or so a couple of the kids have become non stop at the door. They seem to be out most of the day at the weekend, we're happy for ours to go out for a bit but weekends we want to spend together while my husband isn't at work. Today alone they came to the car as soon as we got home asking to play, knocked 3 times across the afternoon, then when we settled to watch a movie and unplugged the doorbell they stayed at the door for over 5 minutes trying the bell, knocking and then peering through the gap in the curtains until I told her a final no.
Our living room window is at the front of the house so unless I keep the curtains shut they can see we are in, and now it's the holidays I worry its going to get even more constant. We're due a baby in the next few weeks and I need to put a stop to this before then.
As it is we've tried ignoring the door when it's a no but they don't go away, if I tell them they're busy they come back later, even when I tell them a time ours can go out they still keep knocking until then!
Kids themselves are around 5 and 8 and seem nice enough, I don't want to be rude to them to get rid of them, and keep it friendly as our kids do like playing with them we just need some boundaries!
I've never seen their parents and don't know which house they live at.
The only thing I can think of is to find out which is their house and put a note through for their parents, but how would you phrase it? We don't want to make any neighbour enemies, and no one wants to be told their kids are annoying, but we can't carry on like
