Congratulations on your baby girl OP!
if I was you I’d seriously think about how you want your family to look in the future.
Ny in-laws do childcare for us 3 days a week as well as looking after other grandchildren. When picking up baby me or DP will also having a cuppa and a quick catch up. My baby is close to the other cousins through grandparents also looking after them. Sometimes we’ll both go for tea straight from work.
On my days off I’ll often pop into theirs and also do some shopping for them on my way in. I’ll sometimes see SIL’s who have also popped in and we’ll all sit with a cuppa and chat whilst the babies play.
Me and DP will also have date nights whilst baby sleeps at in-laws or we’ll all go out for big family meals with in-laws.
10 years from now my baby will be super close with a bunch of cousins a similar age. They will have the security of a big close family around them, not just me and DP.
When I was poorly a few months back, MIL and FIL were straight over with medications as DP was at work and took over baby care whilst I slept upstairs. Then the next day my SIL and her babies were over with supplies for me and watched my baby whilst I went to my medical appointment.
Likewise when my FIL needed to see a specialist I was there like a shot taking him to his appointment and sorting out his medication plan with the doctor and sorting out a complex finance issue for him.
When my SIL had a C-section infection, as she couldn’t drive I took her to the GP as she couldn’t drive whilst BIL went to work.
my other SIL watched the newborn with her baby whilst we did this.
My point is, this kind of support doesn’t happen overnight. Family is about mutual support. Do my in-laws annoy me sometimes? Sure they do, and I’m sure I do them too sometimes. But we all muck in and help eachother and realise the pros of support, love and security that family brings massively outweighs any minor grievances.
So I put up with the hideous tartan outfits MIL dresses baby in whilst I work. In return I get feee childcare from a loving grandparent. MIL puts up with my rants about work and traffic when I get through the door whilst bringing her a bag of her favourite snacks from the shop on my way to her.
Although your MIL is annoying you now, if you nurture this relationship, then it can turn into a wonderful relationship full of beneficial and mutual support.
10 years from now your girl will be at a sleepover at her grandmas whilst you and DP have a much needed date night. Your DD benefits from the feeling of security, belonging and love an extended family brings.
