Breastfeeding is impacted by social, political and financial factors.
Breastfeeding is encouraged as it is the best source of nutrition for babies, but it's not the best for all babies, and it's not the best for all mums either.
Because of this the breast is best campaign flopped.
The Fed is best organisation have been known to be very anti-breastfeeding, but unfortunately have a huge influence over how babies are fed, because so many women lack post-discharge support to continue breastfeeding. This creates a medical necessity to supplement or switch to formula because local councils and governing bodies do not understand the importance of funding community care and immediate access to infant feeding workers, with many infant feeding roles being slashed in entire districts.
Formula companies are also not allowed to advertise first stage milk, but they can advertise follow on milk, which subconsciously makes people think follow on milk is a necessity when it isn't. It makes people think breastmilk is inadequate. Unfortunately our government allow this because it doesn't strictly break the international code of breastfeeding substitutes.
We've also developed a culture where breastfeeding can't be celebrated, lest it be insulting to those who can't/won't breastfeed.
For those who can't, breastfeeding promotion can sting, even though it makes sense to promote something that for the majority of babies is the best thing for them.
For those that won't breastfeed, it can feel insulting to hear the facts about formula and how it can negatively impact babies, ie. If it isn't made with water over 70° then bacteria like E. Coli and C. Sakazakii can thrive, and can kill babies. This isn't about water cleanliness, but rather that formula is pasteurised and not sterilised, and using cold/bottled water and using old formula instead of fresh can increase the risk of bacterial proliferation.
I don't feel like any one should breastfeed if they don't want to. I don't believe in breast is best or fed is best. I believe informed is best.
But there are some people who just don't want to be informed, because they may have a bias one way or the other.
