good point jamaisjedors.
to pick up another idea further down by pigletmania, sorry I am not picking on you just that I wanted to address this one earlier but was too busy:
"What if they still want to do it when their 8,9,10 when do you draw the line and say no? What if they are in school/middle school and still want to be bf on demand not just in the morning and evening, when they want it, especially in public. What if they have a sleepover or stay over at someones house and want a bf before bed. Imo its limiting the child, like tying the child to the mother."
your lack of experience has portrayed scenarios which have no basis in the reality of extended breastfeeding. If a child wants to go to a sleepover they will be too excited, even if the sleepover is at their house, imo, to think about breastfeeding. Mothers who EBF can go away for days at a time or longer and the child will happily settle for the cuddles of another familiar carer. When mum returns home, a feedy cuddle is a way of renewing that bond and the child gains a sense that all is still the same in their world.
This is what DR Jack Newman says about breastfeeding past 2 yrs old...
"But I want my baby to become independent
And breastfeeding makes the toddler dependent? Don?t believe it. The child who breastfeeds until he weans himself (usually from 2 to 4 years), is usually more independent, and, perhaps, more importantly, more secure in his independence. He has received comfort and security from the breast, until he is ready to make the step himself to stop. And when a child makes that step himself, he knows he has achieved something, he knows he has moved ahead. It is a milestone in his life of which he is proud.
Often we push children to become ?independent? too quickly. To sleep alone too soon, to wean from the breast too soon, to do without their parents too soon, to do everything too soon. Don?t push and the child will become independent soon enough. What?s the rush? Soon they will be leaving home. You want them to leave home at 14? If a need is met, it goes away. If a need is unmet (such as the need to breastfeed and be close to his mother), it remains a need well into childhood and even the teenage years.
Of course, breastfeeding can, in some situations, be used to foster an over-dependent relationship. But so can food or toilet training. The problem is not the breastfeeding. This is another issue."
