I was BF for 6 weeks, then onto formula, like another poster said, that was the "done thing" back then, also my mum was 17 years old, had no support from the hospital etc, and was the first out of her friends and family to have a bay so felt she had no "role models" as such to show her otherwise.
She tried again to BF my next brother, with no success, inverted nipples and no support.
FF from 4 weeks...
My next brother she BF for 6 months until he kicked her so hard in the boob, she ended up with raging mastitis, dad still likes to tell the story of mum sitting in the bath, sobbing with pain and expressing "thick pus" from her breasts... niiice, not!
Then with my youngest brother, she did it, it all worked, and he was fed till he almost 2! mum always said it took her that long to work out how it all worked and to have the confidence to do it!

I had an aunty or 2 who were very pro bfing, I do recall them bfing their children, most however did bottle feed with formula.
Mum has always been a huge support to me with BFing, she always said she wished she could have done it longer with all of us.
I have Bfed DS for 17 months now, we will see how long he goes for...
