I would appreciate some advice on whether I am being unreasonable please.
We have been invited to the wedding of my DH's family friend that is taking place close to where my DH grew up. Wedding is in two weeks time when my baby will be 9 weeks. We declined the invitation to the reception prior to baby being born, as we didn't want the couple to pay for a meal for us etc when we weren't sure we can make it, and agreed we wouldn't go but would aim to go up and stay with MIL and go to the church if we all felt like it after the birth.
Now baby has been born, DH and MIL are keen for us to go to the church service only. It is a 3-4 hour journey to get there, and as my MIL has decided to have lots of work done to her house at this time, we can't stay. She expects we'll drive up for the day so around 8 hours of travelling, plus breaks for feeding/changing etc or stay in a hotel nearby. As I am almost solely EBM at the moment, with one FF a day, it isn't exactly practical. I don't wish to be using the breast pump on the motorway or at the service station to be honest. More importantly though, I don't want my son stuck in his car seat for so long in one day, against all guidance.
Am i being unreasonable to say we shouldn't go? I feel it's not fair on my son to be in the carseat for so long in one day. I'm being made to feel I'm being awkward, when I feel MIL is being more awkward with her demands for us going 'as a family' for her to show off her new grandson when she's not able to accommodate us due to her choice to decorate now...
