As usual the discussion goes this way because it is a volitile subject.
I have an extensive burn injury that renders me with one operational boob. Yet I fed twins without supplementing. This was probably becuase I had good support and we watched for it not working, I would have supplemented in a flash had I not been able to give the girls what they needed.
I had support, I had good easy births, and the babes were healthy and never left my side (well son #1 was "so I could rest" and I had problems until i got to my out-of-hospital LC 3 days later). Maybe that is why I never encountered problems. I work to help prevent problems. if a mom says to me I'm adopting I say "did you know you can breastfeed an adopted baby, maybe not 100% but if you want i can show you how", if a mom says "I had breast reduction I say " you can still breastfed, maybe not 100% but if it means that much to you, you can try". if a mom says I quit breastfeeding but I wish I hadn't i say "would you like to ge your supply back, maybe not 100% but if it means that much to you, i can help"....and on and on...
he theme..the mom must want and she must have committed help.
the birth process has become so far from normal that to expect breastfeeding to begin normally is near impossible. It is called the side effects of our choices, or the side effects of the interventions applied to the birth process.
