I’m sure you have held an infant, completely helpless, very hungry, in your arms. They depend utterly on you to protect and nourish them. Their intense, desperate delight as they grab the bottle you offer, shows their utter focus on themselves and their complete dependency on you for survival. It’s a precious memory to feed an infant.
Picture an older child, teen, or adult in that same scenario, however, and you get a completely different reaction inside. It’s repulsive. They should be actively engaged, handling a fork and knife (or chop-sticks) as second nature. The expectation is pretty simple – lose the bottle! Grow up!
