NK, Don't worry, this is the reality for many, many people. This time is the HUGEST learning curve of your life...you are recovering from major surgery, and you have a person in your life that you just don't know yet.
I had moments in the early weeks of thinking "this is the worst thing I have ever done". But then other days, little flashes of feeling would wash over me, fondness...then one day I looked at ds and thought "I love you, but I don't know why". The feelings just build on each other and grow; until one day you realise you love this person more than anything on the face of the earth, and you understand the meaning of loving someone with every fibre of your being!! It will come, do not worry!
Your body and brain need time to grow these feelings. I've always felt that if I had a second child, the bonding thing would probably be a lot easier because my brain already has these pathways that make up the maternal, protective feelings. I think you're at the stage where your brain is making these pathways but they certainly will come.
Be kind to yourself, make sure you are getting the time and rest to recover physically and mentally from your difficult birth; TALK about it!
By the way, smug mothers in magazines = about as removed from reality as airbrushed, siliconed glamour models are from the normal female body. Don't buy it!
