I DO nurse in public. I am however one of those that practice modesty. As I mentioned in a previous post I walked right through the local grocery store while nursing and no one knew what I was doing. Forgive me if I took your post wrong but nursing infants and schedules do not work well together. It is impossible to always predict when an infant is going to want to nurse and it is not always possible to leave. This entire thread has me a bit upset that some can be so callous about an infant's need/right to eat when and where they need to.
Oddly enough, my nursing sister says the only way she can handle the three kids is to maintain the schedule.
But as I said several times upthread, if you are doing it discreetly enough, by definition I won't notice you doing it.
