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?
We had 3, and each time Mom was unable to produce milk. She tried every time, because free milk is better than paying for it, but it just wouldn’t happen.
All three came out perfectly healthy. The first two were dubbed “gifted”, the third probably would be if she gave a fuck about school.
