I always hear that stat blased around the place like it's evidence that there isn't enough 'support' for breastfeeding. I couldn't see it more differently.
I believe that the reason FF rates are higher is because the majority of women simply don't want to breastfeed. They all have their own exact interpretation of why that is, and don't need to explain it to anyone. Maybe it's for the sake of their careers, finances, mental health, other trauma which makes them feel uncomfortable 'exposing' themselves in public, childcare reasons, health reasons, etc. None of this is anyone else's business and no one should have to justify why they want to FF.
Secondly, in the UK we have access to every single tool that makes FF a breeze. Perfect prep machines, lots of different bottle designs, lots of different formulas which work for most babies, especially ones with allergies. Powdered formula for home, pre made formula for days out. Formula feeding is a bit of a faff in regards to bottle washing and sterilising but it is as quick and efficient as it's ever been. We also have access to homes with electricity and safe drinking water. So, ultimately, there's the choice that people in higher BF countries perhaps don't have.
The UK has so much breastfeeding support. There's an entire week dedicated to it. NHS run breastfeeding support groups. You can literally hire a lactation specialist to come to your home and help you. There's facebook groups galore on the matter. Breastfeeding support Instagrams, the works. Do all the countries with high BF rates have anywhere near the same amount of government implemented support? No.
The only difference, in my opinion, is societal. We are very isolated in the UK in the sense that we don't live with extended family members in close proximity. Most of us tend to branch out and leave home well before having a baby. Baby rearing is done by one or two parents, not multiple grannies, aunties, friends of the family, etc. So breastfeeding is probably a lot easier in those environments as you have a lot more time to rest. Here, you probably have to juggle other children and responsiblities on your own, which I would imagine makes it much harder to focus on establishing breastfeeding.
We aren't going to end up living with our extended families once again, so I can see our stats staying around the same level they are. It's obviously very sad if breastfeeding doesn't work out for those who really want to do it, but other than ensuring that every area receives the same level of support rather than lots in one area, and minimal in another, I don't think it's the fault of how much 'support' in place. Women just have more options now.
