How do you shut this down?

[Pillowcase123]

My DP and I have been together for 5ish years now.

I get on well with his parents, we visit them a few times a year and they come and stay with us every few months (in normal times). My DP is an only child.

Every time a holiday/admin thing comes up, my DP's Mum messages me to 'remind' me. This week, I've had 3 messages about Mothers Day and how nice it would be to get a card from DP and one for DPs Nan. This happens at Christmas, Easter, Birthdays etc.

I take no responsibility for my DP getting cards/presents etc for people. He's an adult. And for what it's worth, at least for every year in the last 5 years, he's never missed a birthday/anniversary/holiday and always spends a fair amount on them.

How can I get her to stop "reminding" me or expecting me to take this admin on without offending her?

I've tried saying "thanks, I've passed the message on", I've tried ignoring her and still more messages arrive...

Just say ' You need to message him , he does his own admin. Hope you are all well x '

I would just ignore it tbh for all the time it takes to read it it just wouldn't bother me.

Either that or say thanks but he has reminders on his phone so you don't need to worry about reminding him.

Ask your DH to tell her to stop. She probably thinks he’s never missed a birthday because of all her reminders that to you. He needs to set her straight

Yeah, I think she just assumes I do it all. I've told her he's an adult. We both work full time, I actually work slightly more hours than him so no idea why she thinks I also want to keep track of his cousins birthday too
