With both, probably around 7 or 8 weeks I started to feel that mama bear protective instinct which I think of sort of as a bond. I pretty much completely disconnected with DS when he was born though.
The birth was not at all like I had wanted and I didn't get that rush of ooey gooey love junk. He had a series of issues that led to him screaming nonstop from about day 2 until he was 5ish months old when we stopped breastfeeding and switched to nutramigen. I didn't start to feel bonded or connected to him until then.
