Woke up at 4am, thought I'd had a contraction but decided I must've dreamt it. Lay awake for 20 mins then just as I was drifting off to sleep I felt a pop and my waters broke!
Got up, wandered into bathroom and stood in bath (!) and contractions started. Told DH to get phone so I could call midwife, by end of phone call the contractions were less than 2mins apart.
Got DH to lay duvet out on living room floor and I knelt on that and leaned over my birthing ball. Contractions very painful. Midwife took 40mins to arrive as was finishing up at another home birth first!
By time she got there I was in a lot of pain. She sent DH straight out to her car to get gas and air but then realised there wasn't a mouthpiece in her kitbag. So no pain relief for me.
Labour progressed very quickly, 2nd midwife arrived and DD was born exactly 2hrs after my waters had broken. As she was born she turned and it was then they realised she had been back to back. They declared me a hero for having no pain relief haha!
DD was my 3rd baby, my eldest two were then 12 & 8. They had woken up about 30mins before she was born - think it was when 2nd midwife arrived - but spent the time making me cards to welcome the baby and were actually playing darts in playroom as DD was delivered! With them being the ages they were they didn't need any supervision, DH just popped out a few times to reassure them that all was ok and to ignore my shouting!
Anyway, DD born, placenta delivered, DCs came in to see baby and then I had a bath while midwives cleared everything away. 30 mins after dd had been born you wouldn't have known I'd delivered her on living room floor, the room was spotless.
Tea and toast on sofa, kids went off to school all excited and DH and I spent the day slightly bewildered trying to get our heads around having a new baby without having left the house (other DCs were hospital births).
Worst part was probably waiting for gp to come round, was supposed to be at lunchtime but didn't arrive until 7pm. He then trod on my bare foot with his shoes on so had a bruised foot to add to my grazed bits and horrific piles 
Was gutted when I had to have dc4 in hospital 2yrs later due to complications though, I loved my home birth and can't recommend it enough. Good luck!
