Hi AngelDog I'm planning 2nd home birth in just over a weeks time (I hope!).
My MW visited us at home at 36 weeks to talk through everything and left a list of useful things for us to have:
clean old towels and sheets
kitchen roll
cushions or pillows
large plastic sheets eg shower curtain (pick them up in the £1 shop)
Torch and candles
angle poise lamp
If using pool - mirror and sieve
music
camera
For mum:
something loose and comfy for labour
face cloth
maternity pads
comfy big knickers
refreshments and snacks
For baby:
clean soft old towels
carry cot/crib
nappies
baby clothes
What I did last time was sort everything into two piles; one that I would need if had to transfer to hospital and one with the stuff that would stay at home. I packed a bag with all the stuff we'd need if we ended up in hospital e.g stuff for me to wear during and after birth, baby clothes, snacks, and my TENS. The rest eg old towels, angle poise lamp, plastic sheets went into a big box in the dining room. I also packed a bag for DD just in case she ended up elsewhere, which she did, with change of clothes, nappies, toys, books etc.
It's really useful to have everything to hand when it all kicks off without having to send DH all round the house to find stuff. On the day I sent him up to change our bed so we all climbed into clean sheets with the new baby, lovely.
The MW will bring all the medical type stuff you need. They will also clear up afterwards.
When you go into labour as well as putting water on and turning heating up, make sure any outside lights are on or tie a balloon or something to the door to make it easy for the MW to spot your house.
If it's possible to ask a favour of friends locally do make some arrangements for your DS just in case you have to transfer in or decide on the day you'd rather he was elsewhere. This time we have a list of friends who have all agreed to take our DDs until the grandparents arrive (they live 150 miles away so it'll be a few hours) if needs be and we'll contact them depending on their availability. I'm hoping it'll be night time in which case I'd happily leave them upstairs sleeping while I labour downstairs after last time I'm pretty sure they wouldn't wake.
Very best wishes with everything.
