MIL seeing other family AIBU

I can’t decide if I’m being unreasonable here or DH family are..

MIL & FIL have my 2 DS for us on a Thursday. This is a temporary arrangement until April as I’m required in the office once a week now. They offered. They also collect DD from school on a Thursday as wrap around care is off for the foreseeable. This is also until April. They know full well that we haven’t been seeing anyone.
DD came home on Thursday talking about the pictures she had done with her cousin after school. Apparently SIL went in the car with FIL to collect DD from school as SIL and niece had been at PILs all day with my sons so niece could play as she is bored at home.
DH spoke to his brother about this and apparently MIL had called SIL on the Tuesday to suggest the “play date”.
I get it’s boring. I get they’re probably fed up. But to be honest I feel pissed off that they went round knowing my sons were there for childcare reasons and also pissed off that they didn’t ask if I was ok with them being there, especially as it was pre-arranged.
We haven’t seen my own family or any friends for months now. We didn’t see either side of the family on Christmas Day to keep it fair. My DD didn’t see any family or friends on her birthday. We’ve stuck to the rules and having to ask to become a childcare bubble was hard for me because we’ve put in such an effort since last year to limit our contacts. DH is working every day and I’m working in my office alone one day a week so don’t see anyone at work. I have our shopping delivered.
SIL, on the other hand, went to a friends baby shower last weekend and has continued meeting up with friends and her own parents like nothing is wrong.
It’s really pissed me off and I am unsure whether to call my line manager to ask if I can continue my Thursdays at home again, or do 2 evenings when DH will be at home.

So, do I say something to PIL and email work, or do I leave it as it is?

YABU - there is no problem here. You’re the twat.

YANBU - PIL shouldn’t be having other people round when they have DS and should at least of asked first. They’re the twats.

The whole point of the instructions not to mix with more people than you absolutely have to is because every single interaction increases the opportunity for the virus to spread, so every interaction avoided cuts off a path of transmission
You know this. I know this. Everyone with common sense knows this.

Unfortunately there's enough people, as this thread and countless others show, who think that if you're not being a hermit then you've got no grounds to expect people to follow the rules.

As ever through the last year, there's a substantial number of people who think that it's just other people who spread covid, so they are fine to have play dates / have family meet ups / mix households when they are bored / travel around places because they would rather go somewhere new / go to a baby shower etc.

School is allowed though. As it work. Household mixing because you fancy it, is not. So whilst yes that's risk with school, you are doubling the risk with mingling with SIL. Whether people like it or not, they are the rules. So just because school is a risk (it is, i agree) that doesn't mean you throw everything else out the window and run around doing as you please?

Maybe that's what everyone is doing and we'll be bloody locked in forever because of it!

I’ve said YANBU because they should have asked. But the greater risk is to them and you DN and SIL.

YABU for calling them twats when they’re doing you a favour.

I'm not voting because I'm in the fence here - if your dd wasn't at school then I would agree with you. Because she's at school then that is your biggest risk of having to isolate.
I had a similar incident in December we are in a bubble with mil (she lives alone) ds was with her and sil brought both kids to have a 'play date' - I was livid because ds hadn't seen anyone except mil and neither had I, dh tried to defend them until I pointed out that if we had a phone call to say one of them had symptoms / to isolate then we would have had to isolate the whole of Xmas or even worse could have contracted it.
I understand mil wanting to see her other gc, but we make the effort to ensure she isn't lonely and they don't. It's really hard.
