When I was 4 days old, my mother had a nervous breakdown and was in the hospital for 9 months. I bonded with my aunt and grandmother. When I was "returned" to my parents, I thought I was being given away, that I had done something wrong. I was 35 before I realized that and that had caused me to feel rejection so harshly. I was not even a year old when that happened. You're right. Babies, like ducks, bond quickly. If that bond is broken, for any reason, that pain remains.
