My MIL is fairly low fuss about these things.
My mum wants the royal treatment. My first mother's Day, my mum insisted we all went out for a meal as it was her first one as a grandmother
for context, DS was only 3 weeks old, he spent the first week in SCBU, I was trying to BF, bleeding, leaking, an emotional mess. All of that disregarded. I spent the morning sobbing because I didn't want to go.
I finally confessed to my dad in tears, and he put his foot down that my next one, I could go as I liked. As it is, DS has autism so wouldn't cope in a restaurant now. My life is stressful so I'd rather something low key, just a chilled day and a takeaway. My mum has settled a bit now.
Father's Day, we might go for a BBQ over my parents garden (DH doesn't mind) but it's entirely up to him.
My parents have had their fair share of the focus on them, it's time to concentrate on us. If my children have their own families, I'll ensure they do what THEY want
