So besides being really awesome to look at and touch, breasts are great for feeding baby humans.  New moms often fall into the breastfed vs formula fed trap because what no one tells you is that NO MATTER WHAT, you will be wrong.  Breastfeeding? WRONG. Formula? WRONG.  Just take it from me, and tell no one how you plan to sustain your babies life for the first year.  After that you can go on to debate to Capri Sun or not, but those discussions are much less heated.
I say breast is best for now, because it will change in a few years. It all goes along with what “society” (read affluent people) deems appropriate.  Lemme splain:

(This is like SUPER condensed)
There was a sudden shift that occurred, a shift that dealt with just what kind of role women played in society.  Women looked to be liberated and free of society imposed traditional roles. Educated women wanted more out of life, careers, interests outside of the home, social lives that were rich and satisfying. As such, the idea of barefoot and pregnant became synonymous with poor.
Yep, just like that.
And if the new modern woman chose to take a husband, and chose to bear him children, it would once again be on her terms.  If an affluent, educated, career minded woman wanted to have baby, but couldn't take off work? No biggie, we can afford day care and bottles, formula, and disposable diapers.  She can have that baby, and be back at the office in a week. Poor women didn't have that luxury, and bottle feeding became a status symbol. Breastfeeding for the first time in human history was no longer the preferred method of nourishing our offspring.
Then the whole thing happened in reverse.  Every educated mother knows now that "breast is best", and now affluent women have office jobs where they HAVE to be provided (by law) a space and time to pump while away from baby.  And about that pump, which costs hundreds of dollars to buy, plus some money for upkeep; that's just the cost of being a good parent.
To the those women who work jobs that don't have a quiet private place, or don't provide time, or who can't afford the cost of pumping; its just too bad.

At any rate, breastfeeding was never the only way to feed your baby. 
I chose to breastfeed both of my children.  Squish until she was about 19 months old, and baby boy until 15 months.  Why did I make that decision? 
1.       It’s easy.  No bottles to wash, nothing to mix or warm. No going to the store, no packing things to take with me on outings, no worries about bottle temperature, just super easy.
2.       It’s free.  That’s right; as long as I chose to wake up and eat food every day, I will have an infinite supply of food for my baby
3.       I’m not big on factories.  I eat tons of food made in places not my home, but that does come with the risk that something upstream can potentially make its way to me, and then make me super sick (or rich or sexy…but most likely sick).  So, I try to avoid all factory made foods for baby up to a year.  If I didn’t make it at home, baby won’t be eating it
4.       It’s natural.  God made my body to do this, and I am utterly amazed at the fact that it works the way it does.
5.       I’m smug.  I get to quietly show how much more I love my baby than you, by detailing all the sacrifices I’ve made to feed them this way…wait…  

So about #5.  This is what people tend to perceive, what some people actually put out there, and what really sends these types of conversations into a tailspin.  Listen, hear me now and hear me good: No one, no one, no one (sorry Alicia Keys), can tell you the best way to care for your baby, or make you feel like you’re not doing a good job.  Especially the second part.  I know the pressures all too well, but the way I see it, if some mom was like “What? You don’t give your baby crack?  My baby lives on crack and can’t go without it.  Your baby is obviously missing out on something important by not getting crack”. I would say thanks, and politely excuse myself to go judge the crap out of her.  Why is that? Because this person’s opinion doesn’t count to me. 
We run into trouble when well-meaning folks, whom we care about, tell us that we’re all jacked up, and not directly so that we can get defensive, but passively so that the idea can fester in our brains for days and days until we come the same conclusion that they had all along: we’re terrible mothers.
