Thanks everyone, I think perhaps Lulu is right, it is probably just the reality of having a maximum of a week to go, and knowing the birth is coming no matter where I am!! DH has said he could stay home from now on which would give us a chance of being able to sort MIL out, but it really isn't practical for him to be away from work until he needs to be, especially at this time of year.
I have this sweep booked tomorrow and as long as she does it this time instead of making another silly excuse, if that doesn't get him moving, I really don't think anything except a proper induction will TBH. I think we are going to go with the plan of if circs are right and we can use nextdoor neighbours for DS, or at a pinch DH's mum, then we will and I will go to hospital, if not, then we are all set here for the homebirth.
MIL is a touchy subject at the moment, when I first started having the contractions and I'd seen the consultant she told me if the contractions were to get regular again I was to go straight to hospital, we asked DH's mum to come and stay at our house that night in case we needed to go, bearing in mind I was 33/34 weeks then so if he'd have been born then there was likely to be some complications and that she had already said she would stay at ours when the time came, but on the day she said she couldn't because she didn't want to leave her cats, her boyfriend lives with her so it isn't as though we were asking her to let her cats starve for a night or anything, but she didn't want to do it. So now, even though she still says she would come if we needed her to, we can't really trust that she actually would.
And that is it, no more on the subject of MIL's - or not mine anyway - because I am likely to start swearing very badly!!!
