I had my first child at St Georges and the second at Kingston. Both were planned c-sections and went well. Personally for me Kingston was so much nicer, I had my own room and really lovely nurses plus I got to stay in an extra night which really helped with recovery after the operation.
St Georges for me was a totally different experience, as I was on a ward with three others and my screaming newborn. I couldn’t wait to get home and felt as though I was rushed to get myself up and moving. I totally understand the demands of a busy hospital but if you want a nicer experience I’d recommend Kingston.
