I'm surprised you haven't had any responses so far. I had ds1 at C&W. Can't fault many of the staff, but they were so stretched that the service really wasn't very good. I was in the antenatal ward beforehand, because of suspected pre-eclampsia, and the midwives on duty when I went into labour seemed reluctant to admit that I was really in labour. I had to make them call dp (who had gone home for the night) and most of my labouring was on my own in my little cubicle, with no TENS machine or anything. When they finally bothered to examine me (ouch) I was about 5 cm dilated already. They rushed me into the delivery suite and ds1 was born 2 hours later. The midwife I had for the delivery was far better, although she did make me lie down on the bed. (I heard her say 'if you lie down you are less likely to tear', dp heard her say 'if you lie down it is easier for me' .)
But I also didn't appreciate the postnatal support. I really think, in retrospect, that if I had had more support with the breastfeeding, ds1 wouldn't have had to go into special care at 3 days old. He spent most of the first few days screaming and one of the midwives even implied that i was making him upset and offered to take him off me for a while. He was just bl*y hungry and they should have helped me to feed him. In the end it took him having seizures, and then they decided to do a blood test which showed that he was hypoglycaemic. Our discharge had been delayed, because my blood pressure wasn't coming down, otherwise they would have sent us home earlier, as he had passed all the 'new baby' checks by the paediatrician. That night in the postnatal ward, without my son, and all the other babies crying, was hellish.
Once he was in special care most of the staff were brilliant, but I think that whole situation could have been avoided.
This was 6 years ago, mind you, but I suspect that staffing levels haven't improved much.
I hope you get some positive stories too. To be honest, when I went for the initial visit I was far more impressed by C&W than our other option (Kingston) but maybe the person doing the tours is just better at C&W!
