Your latter posts indicate that you want to know more about it. You would have received a far better response if you had opened with those posts, not with nasty words.
The majority of people do not set out aiming to feed for a number of years. Many aim for six months, and many for a year. Many are aware of the WHO recommendations of a minimum of two years, but, when you are pregnant, or have a newborn, two years seems like a very long time.
What I think is important to remember is that no one just picks up a toddler and starts breastfeeding. They have been breastfeeding since that child was tiny, and they have fed them, every day. Those days have ticked by, and all the little targets they have set themselves to aim for have as well. Suddenly they find themselves approaching six months, a year, two years, three years... Things are going well, both mum and child continue to benefit. Why stop when they're both happy?
A toddler doesn't feed as much as a newborn, so it's not as if you're feeding every two hours for three years!
I made the decision to allow DS to self-wean. He did so, just before his third birthday, having dropped himself down gradually with the number of feeds. It was the right decision for us both, I'm proud of it, and yet if you had told me when I was pregnant that I would be breastfeeding at nearly three, I wouldn't have believed you.
'Extended' feeding is completely normal, anthropologically speaking. Unfortunately our society has been infiltrated and impacted by companies such as Nestle, who have encouraged us to see this as abnormal and unnecessary; "why bother when you can just give our wonderful formula?". So your views, as much as they have irritated me and many others, are not purely your own. You have been conditioned to think this way. Sadly like a large number of people around the world.
Open your mind, read what people have said, ask for support and information when you would like it. No one is saying you 'have' to feed for numerous years, but don't just those who do, and remember that your life may just work out that way too.
