To not want husbands family keep turning up unannounced?

[Lockergooge]

Title says it all really, I get on absolutely fine with husbands family but particularly my MIL and SIL with niece keep randomly turning up unannounced!
I have tried in a nice way to ask them to please give me a call or text before turning up but MIL gets all offended and she doesn’t seem to understand why I’m annoyed.
The other day my SIL turned up and dropped my niece off and said she’d be back in 10 minutes to come and collect her. I didn’t know they were coming (or that I’d be babysitting for 10 minutes) and I’m starting to get a bit annoyed with the unannounced visits.
I’ve started locking the door now but they used to literally just walk in! Or knock once and open the door immediately anyway.

Am I being unreasonable? Am I hostile? Is it too much to ask just to give me a quick tinkle before they pop in!?

I hate this too. One of my neighbours has a habit of letting herself into the kitchen and the first I know about it is when I hear her saying (loudly) to the dog "Is your mummy home? I used to hide from my MIL who turned up all the time, and eventually went no contact as she refused to accept any boundaries. We patched things up when she learned to make arrangements rather than assume we were available.

When/where the 'pop in' culture was prevalent, there were no phones, so not easy to give advance warning anyway.

Yes and possibly closer knit communities. Dgm was on route to the town

My ILs used to just pop in at the most inconvenient times, and just walk straight in. That was just what they did in their house, but we didn't and I hated it.

Came out about 30 years later that they would arrange a lot of these visits with DH. He would say it was OK, but not tell me because he knew I'd be annoyed . So where I was getting annoyed about how rude they were, they probably thought the same about me .

It’s an invasion or privacy. I would never dream of doing this with my adult children. I make arrangements before for a mutually convenient time. I am sometimes tied up myself after all, as I still work.

They need to respect your boundaries and your right to privacy.

What did you do to him when you found out? I hope divorce was in there somewhere.

@Lockergooge

DH is usually at work when these visits happen but I think it should be him to say, rather than me. I have said to MIL when she randomly turned up that now is not a good time and could you please let me know when you’re coming next time. She got really offended and told my SIL and they were both a bit off with me for a while. But she still does it. They have made me think I am unreasonable. Thank you for your answers, it reassures me I am not mean

"She got really offended and told my SIL and they were both a bit off with me for a while. "

Sounds like you did 100% the right thing
