Well, I'm a mother and a daughter. My mom and I had some falling out in my teenage years, nothing compared to this situation, but mostly teenage hormones flowing.
As for the bond: I had children relatively late in life, gave birth at 33 to twin girls. I felt them grow inside me and the bond for me started then. Then, they were born, and THE INSTANT they were born the bond started. These children were from us! And my husband and I vowed to make their lives as wonderful as possible. They grow, they develop, and the leaps and bounds in which they do this is amazing. My girls are 3, going on 4, now. I have bottle fed, diaper changed, potty trained them to where they are now. It happens fast, but the more and more you are around them, the more the bond grows. I would literally kill for my children. I would walk the ends of the earth to find them. I am an animal lover too and would do the same for any of my pets. I can't explain the bond in words, and I didn't understand it until I had children, but it is there, it is strong, and a mother's bond is as strong as a grizzly. Stand back if you mess with mine, cause h-e-double hockeysticks will break loose!!!
I hope this helps...it is very hard to describe.
