How is based upon convenience for the mother? If the child isn’t latching or if the mother isn’t producing enough then the baby is starving. Sometimes, formula IS the best option for a baby so he/she doesn’t starve. Sure, it would be great if every mother could get her baby to latch and make enough milk but it’s just not reality. It’s shaming mom who can’t breastfeed for whatever reason to simply call it giving up for convenience when they are simply just trying to feed their baby.
