Whether feeding your newborn by breast or a bottle, you may be stumped as to how often to do so. Generally, it is recommended that babies be fed on demand - whenever they seem hungry. Your baby may cue you by crying, putting fingers in his or her mouth, or making sucking noises.
A newborn baby needs to be fed every 2 to 3 hours. If you're breastfeeding, give your baby the chance to nurse about 10-15 minutes at each breast.
Some newborns may need to be awakened every few hours to make sure they get enough to eat. Call your baby's doctor if you need to awaken your newborn more frequently or if your baby doesn't seem interested in eating or sucking.
Babies often swallow air during feedings, which can make them fussy. You can prevent this by burping your baby frequently. Try burping your baby every 2 to 3 ounces (60-90 milliliters) if you bottle-feed, and each time you switch breasts if you breastfeed.
if your baby tends to be gassy, has gastroesophageal reflux, or seems fussy during feeding, try burping your little one every ounce during bottle-feeding or every 5 minutes during breastfeeding.
