I was at the roller skating rink with my 5 kids (including my teenage son) and 2 mothers from our school and their kids (yes including more teenage boys) I had worn my new size 14 shirt (i was so excited about the size I didn't about breastfeeding) that I had to button down exposing my whole breast to feed. Well of course he needed to fed. My choices was to stay there in the stands and watch the other 4 kids and feed where everyone got eye level view or head off to the empty cafe where i couldn't see my kids.
I choose to stay where I was and feed. My friends teenage son came over to ask me a question. Not once did he bat a eyelid. He asked question and went off like it was just a nothing thing because it is just that a not a big deal.
