Feed your baby as often and as long as they want. Make sure you're nursing at least 8 to 12 times per day. Some of these feedings might be close together (cluster feeding). And then your baby might rest for a few hours. Let your baby nurse as long as they would like. When done, they will stop swallowing, relax their hands, and fall asleep.
If your baby hasn't nursed in 4 hours, you may need to wake them and offer your milk. Newborns tend to be very sleepy and sometimes will not wake to eat. If your baby doesn't seem interested in nursing, place them in just a diaper against your bare skin (skin to skin) and continue to offer your milk.
If your baby fusses when feeding, don't worry. Some babies get distracted easily. To calm your baby, choose a quiet place for feeding. It may also help if you breastfeed in the same place in your home each time. If your baby is crying, it may be hard for them to latch on. Gently place your finger in the mouth to help them feel calm. Then offer your milk again.
