formula is a perfect alternative - not milk which has gone rancid in the post
Are you representing formula companies here?
No formula isn't "perfect".
I don't want to get into a breast milk vs formula debate, but you're massively overstating to say formula is "perfect".
It's fine, most babies do fine on it
But, it's not the same as breast milk, we don't even understand what's in breast milk, how could it be? We didn't know about breast milk feeding the good bacteria in the gut until recently, for example, nor how important that is for overall health.
On a population level, there are differences. Breast milk is better, all things being equal.
All things are not equal though, there are other factors that come into play, and for many families, formula may work better for them.
Breast milk is still the ideal though and you're gaslighting mothers to pretend it's not.
Also, please don't refer to this mother's milk as "rancid". That's just offensive.
