Whatmeworry You do come across as having a personal chip on your shoulder about this issue. You began arguing that cost wise there wasn't an advantage to bf, which is utterly ridiculoushmm
It's hardly ridiculous. A baby needs about 500 calories a day, on average, You have to shovel those calories into the mother first or straight into the baby, you can't create energy from nothing, that's basic physics.
And those calories are not free, that's just basic economics. Whether you buy them as formula or as mother's food, it costs you. Nature has a way of making mothers take them on during pregnancy, but they still cost money.
The general rule of thumb in the UK is it costs about £1 per 500 calories for a balnced diet, so about £7 a week. A tin of formula lasts about a week, they are about £9. Do the maths.
You can choose cheaper ways to load up on the 500 calories (crisps and coke, toast and peanut butter) if you prefer, or more expensive (organic veggie diet)
This is very, very basic stuff that even a kid can work out - and yet by pointing it out I somehow have a chip on my shoulder?
Based on your attempted argument to discredit a financial advantage to bf, I'm afraid I don't have much faith in your attempt to discredit all the research to support the health advantages of bf. Tiktok comes across as very professional and well educated in her field. Are you an expert in the field, or have you just attempted to find evidence to back up what you want to believe via google?
Actually, I just read a paper tiktok pointed me too - and it showed her that it, far from casting a benevolent eye on BF as she thought it said, showed that - and I quote - "after taking sibling differences and estimating the within-family model, PVT score is the only outcome (out of 15 tested for) that remains significantly correlated with the duration of breastfeeding". It was pretty much at random.
The difference I think is that, as a statistician, I can actually read these papers and see what they are really saying.
