Following my earlier thread (and thank you to all of you who replied), I sat DH down last night and had a long talk to him about it.
I acknowledged his fears and we talked a bit about them and the 'what if' scenarios and he's agreed that he (a) understands why I want a homebirth if possible; and (b) that he supports me in there, wants to be there and will do what it takes to make it happen.
We've agreed that so long as I have acceptable blood test results at 36 weeks (I have a blood clotting disorder so need prothrombolin tests), manage to get to 37 weeks and the consultant at 38 weeks cannot make a compelling argument against it (backed by evidenced facts) we will attempt the homebirth.
I'm prepared to accept the fact that I might have to transfer AND that I might decide on the day to go to hospital instead, or that I might decide closer to the date I want a repeat cs.
Asking him practical issues like 'where do we put the birth pool/who will fill it/will you do shifts with DD with my mum and if you annoy me or I annoy you, can you swop with my mum and spend an hour with DD instead of me to get a break?' really helped. I'd forgotten that men are problem solvers not empathisers!
So now I just have to order a birth pool and sit tight for another four weeks or so and ignore this tugging tightening sensation in my pelvis fifteen thousand times a day!
But am very pleased that we managed to come to agreement on it, finally.
