Chow.com's Helena Echlin is the internet's answer to Emily Post. There is no topic too sacred for Echlin to tackle. Is it OK to eat on the subway? She can tell you. Can you ask friends to bring their own cups (the drinking kind, that is)? She's got you covered. Her advice is always well reasoned and sensible, which means that she is almost always ticking someone off.
Recently, Echlin took on breastfeeding at a restaurant. Her stance is that if the kid is hungry, mom should feed it. If the sight of a bared breast makes diners uncomfortable, then that is their problem, not the mom's.
In the comments, of course, is where all of the boobs come out. Some stop short of suggesting that moms always stay home. Some just can't handle seeing a breast with a baby on it. Some are more ticked off when mom give her baby a bottle of formula, rather than doing it the old fashioned way.
Which just goes to show you that moms -- especially new moms -- can't do much of anything "right" because no one can agree on what "right" actually is. Try to look at it as liberating.
