Just also to let you know that for all I back skin to skin, and my 3 ELCS were perfect and lovely experiences, you don't have to feel you have missed out if it doesn't happen.
My oldest was born by Em CS with Apgar scores of 1 at 1 min and 3 at 3 mins - and as a result of being, basically, dead, they had to deal with him. I did not see him at all, he was shipped off to SCBU full of tubes before I had a chance (they had taken my contacts out, the buggers, and I was flat on my back with a spinal block in place - and they weren't really very good about keeping me informed, though they did a brilliant job of saving his life).
When I saw a photo of him about 3 hours after delivery he was in an incubator and then a few hours later I actually saw him, all bundled up in a hat etc with splints and tubes everywhere, and that was when I got to hold him. I didn't see him naked for weeks.
All of that said, he and I had - and have - a brilliant, perfect relationship - he actually is my best friend as well as my son. He had no anxieties, nothing - we bonded immediately and he was a perfect baby, a lovely toddler and despite a few rebellious years got straight A*/As in A levels. He is now a strapping six foot 3 and predicted a first class degree, and I don't know a closer mother and son. So skin to skin is lovely, but not essential - life is more important.
