I breastfed my children. I was "gifted" with rather large breasts even before I was overweight so when I fed my children, there was no hiding it without light baby blanket to cover. My children were also the type to eat a bit and then want to look around for a second. They also had a number of allergies and stuffy noses. Had I fed them in a public place, I would have been TOTALLY exposed quite often. I feel that it becomes inappropriate at that point.
It is not just a matter of what our rights are or how natural it is. It is a matter if not causing others to be uncomfortable either. I have the right to feed my child, yes, BUT, I should also keep myself covered while doing so.
Also, when I began to lactate, I did not turn into a cow. I still don't want my breasts shown to the public. They are a private thing and I know my husband would not appreciate them being shown off just because I was feeding our children.
As for feeding in the restroom....NO WAY! They are full of germs and smell horrible. I would never eat in the restroom and my child should not either.
Most of the time, I would look for an out of the way peaceful place. Breastfeeding was a very bonding time for me and my children as well as a feeding time. If I could not find an out of the way place, I would be sure I was covered for me and those around me.
I think seeing a woman who is covered says "Oh, there is a mama feeding her baby". I think a woman who is covered says "Wow, there's a boob!"
