As a mom of the same age- who has nursed in OG twice- once with a NB, before I had researched and discovered I shouldn't be ashamed for my nursing choices, I cowered in a bathroom- and the second time, with a sixth month old and much more secure, I was in the booth.
But I WILL mention- one, these booths are super crowded and she was probably already uncomfy and wishing she had more room- and two, not everyone has had the luxury of being made to feel good and secure with nursing! Especially women who have families who are weirded out by their bf'ing, or spouses, or (ahem-young moms) those who are in general looked down upon or discriminated against, to BEGIN with. Personally, I am just WAITING for someone to say something about me nursing my flailing one year old- but in the beginning, I was much more meek. Would I have agreed and slunk away to the toilets? Probably not. I would have been pissed, and embarassed, and left. But I can see how a mom might not have had all her strength about her, and given in to an a-hole with no decency or sense at all.
