It happened to me with my first child because of an emergency c/s too. I remember the operation was so quick and sureal. I didn't go into labour as he was in fetal distress, so in less than 20mins of finding out I was going for a c/s I was holding my son wondering if he was really mine. I had no time to get use to the idea of him not being in my belly and being on the outside instead it was just like so instant. I remember the epidural wearing off afterwards and putting my hands on my belly and he was gone and my belly was flattening out. It took me a while to bond with my son and I was upset that I didn't have natural birth I had planned. One day I realised it didn't matter how he got here, he is healthy, beautiful and everything okay. Give yourself time and don't feel bad that you can't bond straight away, it is normal especially after a emergency c/s.
