OP - so glad your heroic DH stepped in and set some folks straight.
My 17mo is a nursing champ. Yesterday I picked her up from her second day at a new (Montessori! yay!) daycare, and offered to nurse her there in the tiny lobby. We plopped down in a chair and started, and suddenly the room seemed full of other parents waiting to pick up their kids - mostly dads. I just kept my eyes locked on DDs and gave her what she needed, but part of me sure did wonder what other people were thinking. I've nursed in public all along, but after a year, I did suddenly start to think about it more, after a couple of comments from family (!).
Wish we didn't even have to give it a second thought!
