Mostly shite really.
With dd1 (stillborn) the pn midwife didn't bother looking at my notes, shoved me into the middle of the pn ward surrounded by newborns, congratulated me on the birth (!) and abandoned me. I discharged myself as soon as I was able. That was Edgware Hospital
With dd2 I had had minor bleeds throughout pregnancy, and because of dd1 was considered high risk. I was induced and had a 3 day labour with an epidural at the end of it. The pn ward was clean and there were plenty of midwives; they just didn't bother looking after the mums, and treated a young mum (about 15) really badly.
With ds I had an emcs - had had a bleed earlier during the day and gone in to be monitored. His heartbeat dropped and despite my dh shouting at the midwives, it was pure luck a junior dr came to see what the fuss was about.
Went to pn ward with ds - the ward had four bays with 8 women in each. During my first night there there was ONE midwife for the entire ward; there had been four other emcs done that day, and none of us could move. My ds was put out of my reach and when he started choking, another patient (high forceps) managed to get to him as he stopped breathing.
The second night there, we again had the one midwife; a friend of hers stopped by (another midwife) and insisted on staying the whole night to help her out - she was off duty and did it unpaid!
During the 3 hellish days I spent in with ds, I was shouted at for not knowing I had thrush in my boobs, for not knowing that I HAD to get my own food, for not being able to get myself out of the bath, for getting my dh to bring food in for me, and for shouting at a mw who forced a woman to go to the bathroom (hours after a emcs) and then left her there unable to get back to her bed.
A formal complaint was made, and we got back a form letter apologizing for any 'less than perfect' experiences we had.
Both of these were the Lister Hospital, Stevenage.
