piscesmoon, has someone told you that you shouldn't have stopped at 9 months? You had a good personal reason to stop - that's absolutely fine. Nobody is judging you for it. I'm not sure why then you are feeling the need to judge those who continued for more than 9 months.
"By the time they are running around and can ask for it they do not need it." No they don't need it (most of the time), just as they don't need teddy bears or unnecessary cuddles or pink milk. So what's your point? (Although on occasions when you have a toddler who is sick with a bad cold or stomach bug and won't eat but will still breastfeed, your assessment of this "need" changes somewhat.)
"I am not selfless and I don't wish to be entirely at the beck and call of a toddler-I don't think it does them any good either." Very few natural term breastfeeders continue to feed their toddlers throughout the day - it just isn't practical for most women. For most it is just at bedtimes/in the morning, just as a non-breastfed child might have milk in a cup at that time, so there is no more issue with being "at the beck and call" of the child than there would be if you weren't breastfeeding.
"If you can talk to a 2 year old about abstract ideas such as the meaning of life you can explain that they can have milk out of a cup!" Well obviously they have milk out of a cup as well. If the child wants to continue to breastfeed, and the mother is happy to let it, what exactly is there to explain?
"I think it says far more about the mother than the DC. I have never known a DC upset about stopping, but I have known plenty of mothers who are upset. The DC is excited about the next stage-not looking back." This is just ludicrous. What on earth do you imagine goes on in the households of natural term breastfeeders? That they are forcing their breasts on their children? This is simply not how it works.
