Wow she sounds like she's jostling for power already and getting herself all prepared to be a selfish bloody nightmare!
I would say that you need to set up some boundaries now, to avoid having this battle when you're potentially more vulnerable and easier for her to try and manipulate.
Nb I said 'potentially' not definitely :) but from my experience and many hours mumsnetting, when the baby arrives, and you have so many new things going on, it's very difficult to deal with this kind of thing.
One thing I didn't anticipate was the overwhelming visceral reaction I had to bring separated from my baby. It was like someone was pulling my heart out of my chest and stretching it away from me when Ds was out of sight or if he cried and someone tried to comfort him and wouldn't give him back. I found it hard to deal with and I was very vulnerable to people being selfish about DS, in my case my mother so not a mil hater here! I had done the 'oh it will work itself out' approach which in retrospect was actually the 'head in sand' approach and I wouldn't advise it!
Actually it was like my heart filled with pure fierce love being pulled out of my stomach to be truthful though I know that makes no biological sense!!!
Anyway I digress...
- Be firm but nice now, and reap rewards later
- and absolutely critically, get your DP onside and prepped to be dealing with it if and when he needs to.
- Give a little ground in some ways strategically to avoid it becoming a battle with a winner and a loser.
- And get yourself in a position where you have nothing to feel guilty about. Guilt becomes this massive force and it's so easy to get guilted into doing stuff you really shouldn't be doing for you or the baby.
I read on here over and over again about situations where the Dp basically checks out and let's the partner be treated very badly. It makes me so angry that these men stand by and watch their partner and mother of their child be so hurt and distressed and not give a shit. Grrrrr!
So, start talking to him and getting him to understand that it's NoT ok for certain thjngs to happen, even once, and why. I think some of it is ignorance about what a new mother goes through and that can be cured by getting him inforned And more than that, really empathising.
He doesn't have to be rude or mean to his mother, and maybe discussing it will help him see it's not a 'her or me' thing where he can stand back and say oooh poor me caught in the middle. It's about changing roles and renegotiating practical arrangements when everyone is a bit sensitive and worried.
Setting boundaries now with DP agreeing will help so much, and doing it in a nice way so thinking about a special role you'd like mil to do, or invite her to do x thing, or chose x to buy or arrange etc. this can help and be positive way of managing her expectations and fears, and by agreeing on thjngs you'll be happy for her to do means you won't feel guilty about sticking to your guns about thjngs you just won't do. Don't be guilted into anything!!!
