I didn't know about the UNICEF thing. Eh, it's whatever to me. If she wants to do it, more power to her. I, personally, don't know if I would be able to do it. 1) I don't even know if I want to breastfeed. (Flame me now, idc, but that's my opinion on it) and 2) I see breastfeeding as an intimate thing. It's almost like a time to bond with your child.
Now if we want to get into the breastfeeding argument like Shelby posted - I have no problem with BFing, but PLEASE FOR THE LOVE OF GOD! don't whip out a breast in public.
I mean, idc if you breastfeed in public, but don't go around flashing everyone in the process. Like, there's a difference between discreet breastfeeding (strangers can tell you're BFing, but they can't see nip.) and flashing (stangers can DEF! tell you're BFing and they can see everything)
ETA - And there's a time and place for it too. I'm not saying you have to BF in a bathroom - I don't eat in a bathroom and I don't want to either. But please, don't BF during a funeral, and if you have to please make it discreet. My step-aunt did that during my grandmother's wake and it was very disrespectful. She took her baby, sat down on the wall next to the casket, and fed the child. She wasn't covered either, it was all hanging out. I found it utterly disrespectful.
