In my opinion, you cannot blame the corporations for everything because in the end, people need to be held accountable for the decisions that they make. BUT, there is definitely a push from the formula companies to get babies on formula and not breast milk.
All of the welcome packets from ob-gyn that you get at your first pre-natal visit include formula samples, and when you leave the hospital you leave with tons of formula samples, just in case...
When I had my daughter, I came home feeling frustrated because we were having issues getting her to latch on. This feeling is what corporations capitilize on. The mother is frustrated and wants her baby to eat so she remembers that formula sample she got and it's easy to slip into that routine instead of giving breastfeeding a real chance. Thankfully, in my case, the lactation consultant at the Sacred Heart in Pensacola was awesome

I think if the hospitals didn't give out samples (unless requested, I suppose), then maybe more people would stick with breastfeeding because they HAD to.
Also, on all formula packaging and magazine ads, you will notice they say that breastfeeding is best for your baby. This is because they have to by law, I wonder if they would still include that if they weren't forced to? There was supposed to be a big public campaign (similar to no smoking campaigns) back in 2003 about breastfeeding from the Department of Health and Human Services, which didn't happen because of lobbying from the formula companies.
It's a shame that doctors/hospitals don't really inform their patients about breastfeeding...I wonder if it's because some of them get $$ from the formula companies to handout their specific brand's samples?
As far as WIC goes, why wouldn't they offer coupons(not sure what the right word is there) for breast pumps/supplies as well as formula? Then children would be healthier and think of all the money that would be saved, considering that formula feeding costs between $1500-$4500 a year.
I think that corporations and the media don't help. Any story you hear in the media regarding breastfeeding is always about some lady nursing her older child. I saw a story awhile back on Fox Business Channel about a breastfeeding doll and they were talking about how outrageous it was. I wonder if they think a little girl feeding a babydoll a bottle of manufactured food is gross? In almost all of the books/videos we found while trying to prepare my daughter for the arrival of her little brother showed babies been bottle fed...so there is marketing from the start to push you towards formula.
