I'm 36+1 today and trying to work out what happens when. I've planned to have a home birth, if all goes well, with birthing pool if possible.
DS (3yo) is going to get picked up by his grandma, who lives over an hour away. He is used to staying there and I'm going to do him an overnight bag when I organise my own hospital bag.
I suppose the main things I'm mulling over are the unanswerable "what ifs". Last time, I was in slow labour for a fortnight before DS arrived and we had a few false alarms before it started for real.
So, what if it's not really labour?
What if it's 3am and progresses really fast (I got to 6cm in 8 hours last time, so not at all fast, really, but the midwife keeps saying that second babies are faster) so that it's getting scary by the time DS gets collected?
What if DS sees me in pain and is really worried or scared, before his grandma gets here? Am I going to scar him for life?
What if I tell her to fuck off, or something similarly charming? I'm going to be on gas and air and it basically got me pissed and a bit lairy last time. 
What if she picks him up and the MW arrives only to tell me that I'm not even the tiniest bit dilated?
What if she gets here and there are midwives and placentas and paramedics and blood all over the place and it's total mayhem over which I have no control whatsoever?
What if DH gets offended that he hasn't even had a mention yet even though he's the one who's actually any good in a crisis and doesn't run around flapping like a useless headless chicken but goes all calm and does the right thing?
Basically, I am shit scared and would appreciate advice, your experiences and possibly a soothing "there there"/cup of tea/someone else to give birth to this baby for me. Hayulp.
