I had dd at Lewisham in Oct 2004, and then chose to go back there to have ds in 2007, instead of going to King's, which is also close to me, as I felt the care was good (it is possible that I don't have very high expectations of the NHS).
The midwife from Lewisham who ran antenatal sessions at the GP's was excellent, and took lots of time to be reassuring when I was a first time mum. The actual birth was ok (I asked for an epidural from the outset); I went in with some bleeding (which I now realise was actually a show ), and was kept in until I gave birth 30-odd hours later, rather than being sent home, as I know sometimes happens at hospitals that are busy. My birth plan was kept to, my German midwife did some excellent stitching afterwards (only a small tear), the food was pretty dire (but the puds were good - think old school food!), and I got masses of help with breastfeeding, shown how to bathe dd properly. All very professional.
Downsides: I thought the postnatal floor was grubby, but not a problem as I just used anti-bac spray when I got there. I also got a private room (about £30) after one night of listening to three other people's babies crying, which made life much more relaxed.
With ds, I was urged to try for a home birth! I prefer the safety of being near plenty of experts and all medical stuff in case of emergency, though, so chose to go in. And all went well until he had shoulder dystocia, and there was a team of, I'd say, about 5 people waiting at the back of the room in case it all went wrong. But I was too tired to care, and the mws dealt with it, did Roberts(?) maneuvre, only told me cord had been wrapped twice round ds's neck when he was peacefully bfing an hour later and were, all in all, excellent. They also had a crash team in the room within 15 seconds after dh fainted (the anaesthetist's description of epidural risks was a bit too graphic for him, poor dear ). It's a shame the delay he caused meant I never got my pain relief though.
My neighbour, otoh, had a terrible time at Lewisham, so I guess it's luck of the draw.
