"I would not rather have been breastfed, no. I am perfectly happy to have been ffed. It hasn't affected my life in the slightest"
What, even if it meant that you had healthier blood pressure, a more aesthetically formed palate and face, and were about 6 IQ points brighter than you are now?
You can't know that not being breastfed hasn't affected you because a) you haven't lived your whole life yet b) even if you had it would be impossible to quantify how being bf (or not) had impacted on your life, unless of course you could go back and live your whole life again as someone who had been breastfed in infancy, and then compare.
"Sabire - perhaps Scaryteachers son will just accept that she didn't bf him and move on like most people do?"
Err, yes - I'm sure he will. What choice does he have?
"TBH Id think someone was very strange if as an adult they wrung their hands over the thought that their mother didnt breastfeed them. Very odd thing to feel sad about IMO"
But then I suppose it depends on the relationship they have/have had with their mother, their health in childhood and adulthood, and their knowledge of the differences between breastfeeding and bottlefeeding. If you think breastfeeding is roughly equivalent to bottlefeeding, and a lifestyle choice above all else then you're not likely to care very much about it, are you?
"A blanket claim that bfing reduces these risks doesn't make explicit how long one would need to bf for before these risks were reduced? A day? A week? 8 weeks?"
Breastfeeding doesn't "reduce" the risk of reproductive cancers. Not breastfeeding increases them - women who don't breastfeed have physiologically abnormal amounts of oestrogen in their bodies because they are not lactating.
And in answer to your question, breastfeeding for a few weeks doesn't make much difference to cancer risk - you really have to breastfeed for as long as your child needs breastmilk, which is at least a year, but preferably longer. I have done 5 years of breastfeeding altogether, which I know won't eliminate my risk of reproductive cancers, but will hopefully have some positive impact on my chances of getting them, which I think is all you can ask for.
