Oh...boy.
I can give one personal example, though, where I am not sure if I;d feel comfortable with it, and I like to consider myself open-minded. I suppose I;'d get used to it, but at the time, it was a shock.
I used to work in the shoe department of one of the major dept stores, and one day, a fmily of 5 came in, whenit was crowded and busy. A holiday weekend, memorail Day or something like that. A father, a mother with what looked like a 16-18 month old, and 3 kids. two of whom were grade-school age boys. The older around 9, I'd say. After 15 mins, the baby began fussing, so right then and there, in the middle of a crowded aisle, the mother whipped her sweater up, exposed her whole breast, and jammed the baby's mouth on. Of course, the crying stopped instantly. She didn't exactly expose her whole breast, but she made no attempt to hide it in front of the older boy either. And there were times when I could see he saw it. A few mins later, the baby was done, so so held the baby up and whipped her sweater back down.
Now, I know that children are should be taught that things like breastfeeding and the sight of their mother's breasts is normal, but there should be a cutoff age, esp for boys. I's ceetainly feel a little enarrassed haivng my teenage or post-8 yr old son see me nurse, covered up or no. What do you guys think?
