No one is forced to like someone breastfeeding in public.
No one is forced to look at it.
Starlover seems to think 'not looking ' means sitting with your head twisted at 90 degrees. There are many occasions when I am 'not looking' at someone without needing to do that...I just don't look!
A case in point might be someone sitting at a table near me with very table manners - slupring a bit too much, eating with their mouth full, dribbling a bit, spitting a bit out, dropping lumps on the floor....you know, the way a baby of about a year old eats?
So, I don't look, if I don't like the way it appears.
In fact, to me, the baby of a year eating that way is doing it that way because he is a baby, and it doesn't bother me. But I can accept that others might feel it's all a bit sloppy, and they might not have the same 'aw, ain't it cute?' feeling I have about it!
I would not expect them to fetch a policeman. I'd just expect them not to look...what could be easier? I remember learning 'not to stare' when I was a tiny tot - so someone who had a disfigurement, or a ridiculous hat, or a spot on the end of their nose, was not made to feel uncomfortable by my discomfort. It's called manners, and we should all teach our children the same thing (I have done so with mine).
Neither the baby, nor the mother, breastfeeding in the street is shitting, weeing, farting or belching. The baby is eating - just as anyone is allowed to do in public. It's natural, but it's natural not in the way that shitting, weeing etc is, but natural as breathing, blinking, sweating...and to the baby, as involuntary as all of those things.
The alternative - mother and baby rooms, cafes - are not always convenient (especially if you have shopping, or a toddler, or you are with other people) and why should we be forced to use them?
People cannot help the hang ups they end up with in adulthood, but part of being an adult is to throw away the ones which are meaningless, surely, and live and let live?
I am all for legislation protecting mothers and babies from harrassment, and it will be a powerful symbol of acceptance when we do get that law.
