XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX Right. Breastfeeding is an active effort on the part of the baby. With bottle-feeding, the milk intake is determined by gravity, the size of the hole in the nipple, the aggressiveness of the caregiver and how fast and efficiently a baby can swallow and breath. I completely agree that ALL the studies show that physiologically (heart rate, respiratory pattern, apnea, bradycardia, oxygen saturation, etc.) the breastfed infant is more stable - he is also taking in LESS. Physiologic stress and energy intake and output are two different concepts, and not necessarily related. Yes, you can be more stable, but also consume less energy while exerting more effort.
