Insider secret: paced bottle feeding

If you have to supplement with expressed breast milk or formula, hold your baby in an upright position and hold the bottle in a horizontal position. This position forces the baby to work a little bit to get the milk, more like the flow at the breast. Most people instinctively recline the baby and tilt the bottle, allowing the baby to chug the milk. If your baby chugs breast milk or formula with a bottle, the baby is likely to become very impatient after going back to the breast.
