Effective Sucking

What is effective sucking?

During effective, nutritive sucking, your baby uses the structures of his or her mouth to compress the milk sinuses beneath your breast and move milk into the back of his or her throat to swallow. Initially, your baby may seem to suck in rapid bursts to trigger milk let-down, also called the milk-ejection reflex. Once let-down occurs, your baby should suck at the rate of about one suck a second, pausing only to take a breath with every few sucks.

  • Listen for swallowing. You should hear a "huh-ah" or soft "k" sound deep in the baby's throat as he or she sucks. Some babies swallow softly and other gulp loudly. You should NOT hear a clicking or smacking sound.

  • Watch your baby's jaw. You should see rhythmic movement in the muscle that runs from the lower jaw to the ear when she or he is sucking deeply. You should also notice rhythmic movement that begins at the edge of the baby's chin and travels down her or his throat as baby sucks and swallows. You should NOT see deep dimpling of his cheeks.

Allow your baby to direct feedings. Your baby will detach him- or herself when satisfied. After this happens, you can offer the other breast if your baby still seems hungry. If your baby frequently falls asleep at the breast within a few minutes of latch-on or your baby frequently breastfeeds for 35 minutes on the first breast without self-detaching, discuss this with your baby's doctor or a certified lactation consultant (IBCLC).
