With DC1, I'd been to surgery to be fixed for a 3rd degree tear, and went on a shared ward after. The first night was fine, just me and another mum, and I slept most of the night (couldn't move becasue of the catheter!). The second night was bad, as the nice mum had left, and I got 3 new room mates, one of whom had twins who had to be fed every 3 hours, but instead of the midwives coming in quietly, the mum had to set her alarm for every 3 hours, press the buzzer, the midwife would come in shouting, "who needs me?!" waking everyone up. Plus there were loads more visitors that should be allowed, and the girl next to me was watching tv till 10.30pm without headphones, so I couldn't even nap when the bab was sleeping.
For DC2, she had a mystery infection, and they knew we'd be in for at least 5 days. When the midwife said she was going to arrange a bed, I politely asked if a private one might be available, and she said she was good friends with the midwife in charge upstairs. I was on the ward for the first 3 hours (I had no idea at that point if there was any chance of a private room) and then I was quietly asked to move, and it was to a private room. It was fab, and despite the multiple lumbar punctures and painful blood tests, it really gave me a good chance to bond, and sort bfing. It wasn't perfect, as the door banged loudly everytime the staff came in, etc, but it was so much better than that awful second night on the shared ward...
Just be nice to everyone you meet, and as soon as they mention arranging a bed, ask very politely then...
My main issue with the shared ward was the management by the staff, as it could have been better if common sense was used, and the rules followed...
