Thanks ladies. She is a bloody know-it-all Littleb and your FIL sounds very like mine but luckily he keeps his opinions very quiet. I think you are right, I need to be strong, I don't want this relationship to go on like this. Just spoke to my friend who had similar situation and always said that she thought there would be a power-struggle when I got pregnant - that's exactly what it is, she's the matriarch and trying to exert her control, two alpha females. I am just not good at confrontation, but I am going to turn this rage into something useful and start to set firm boundaries and like you say I can simply say that we've heard her opinion we don't need it again. This is my family and I will do things how I see fit - just wasn't prepared for doing battle with her! thought she'd be a breeze.
Thanks wilde, the stats is a great idea. I think that's what really peeved me, she was treating me like I just thought 'hmmmm, homebirth sounds like a right laugh, let's give that a bash!'. She's known me for years, therefore she should know that I would have researched the hell out of this and decided it was the best for me.
I accept that it can make a mum nervous, and my mum was when I told her but listened to me and has come around, no doubt she is still worried but she accepts it's my decision and will support me and to be honest my mum will just worry anyway!
I think if the situation with MIL were to carry on and I wasn't able to get the situation under control then DH would definitely step in and tell his mum to take it down a notch. But I am normally very much in control so I think the shock of her behaviour and my hormones have taken me back a bit.
I envy you Littleb with your inlaws being far away - bliss! Mine are 15 mins drive! Which is even more reason I suppose to get these boundaries in place.
