However, if your baby consistently awakens and cries less than two hours after feeding, the amount of formula may be insufficient. Most babies feed 15-20 minutes. If you warm the formula, put the bottle in a pan of hot, not boiling, water for a few minutes or use a bottle warmer. Test the temperature of the formula by shaking a few drops onto the inside of your wrist. It should feel warm but not hot.
Most babies do equally well with cold formula.
Do not use a microwave to warm milk, as it can cause severe mouth and lip burns. Nursing babies should be offered both breasts at each feeding. Each feeding should start with about ten minutes on one breast, followed by burping and a shift to the other breast. If your baby seems sleepy after the first breast, you may want to wake your baby before switching to the second breast. It is best to divide each feeding relatively evenly between both breasts so that each receives equal stimulation over the course of the day.
