I typed a long post, then MN froze up on me and I lost it! So, here we go again!
You could have been describing me after my dd was born. Horrible birth, long labour, emergency Caesarean - and for the first two months or so I was in the psychotic hell that Pruni describes.
I can remember my MIL coming in to see me in the hospital on about day 3 then going home and ringing my dh to tell him that I was cold to the baby, I wasn't speaking to her, I wasn't showing her any affection, I wasn't paying her any attention ... I was paying her attention but I was almost on auto-pilot, just doing as much for dd as I had to, because physically I wasn't up to much more than that. I was tired beyond belief, in a great deal of pain, and didn't know where I was to a fortnight. The last thing on my mind was showing joy to my MIL and anyone else about the baby - I was just trying to get through the days (and nights) as best I could.
I won't say I didn't bond with dd, but I certainly didn't love her for the first couple of months. I would have walked over hot coals to protect her because she couldn't protect herself, but I didn't love her and I guess you could say I had no joy about the baby either. It's hard to feel joy when you are tired, sore and struggling to feed when your baby wants to feed for England.
All I can tell you is that it passes. For me, dd settled, I got to know her and eventually to love her. The first couple of months really don't bear any relation to the rest of being a mother. You should also bear in mind that a Caesarean is actually pretty major surgery and can take a long while to recover from.
