I mean, at least a baby should be breastfed (as in a balance between formula and breastmilk) while there are those who solely use formula as their main means of feeding the baby but later in life that child has issues with their immunity like being susceptible on illnesses that are typically not fatal for most people.
That’s because breastmilk has all the nutrients to strengthen immunity later in life for a child. There is a difference between breastmilk and powdered milk: since formula is composed of numerous chemicals (it’s made from compounds) while breastmilk is from the mother. Is breastmilk healthier than formula?
This is the answer. A fed baby is the goal. My wife exclusively pumps, and we supplement with formula when she gets sick or something comes up. The biggest reason I can give you to breastfeed instead of formula is that formula stinks. If you don’t clean a formula bottle up in time it reeks. A half empty bottle of breast milk can sit out a whole day and doesn’t smell much worse.
