An equivalence that does not bear out for baby formula.

Whoever wants to feed their baby breast milk or formula, do what you want. There’s enough anxiety in raising a child, we should be aware of when we might be increasing it in others for no good reason. GP could’ve supplemented their baby’s diet with formula while his wife was gone and everyone would’ve been fine.

Well said. I'm aware of one large-scale randomized control trial of breastfeeding. It found a slight reduction in ear infections and other infections early in life, and no change in IQ in the teenage years. So yes, breastfeeding has benefits, but the amount of pressure people feel to breastfeed is disproportionately high.
