What is Nipple Confusion?

What is nipple confusion? It's a "first world problem" that happens because sucking on a rubber teat requires a very different mouth and jaw action than sucking on a real nipple.

When babies breastfeed they relax and open the mouth wide. Next, they pull the milk out with gentle peristalsis (a wave of muscular contraction passing from the tip to the back of the tongue). Bottle-fed babies, on the other hand, open their mouths less widely and tend to bite the nipple, between the gums, to promote the flow of formula (You can imagine how that feels on your nipple!). This is what causes nipple confusion.

Signs of Nipple Confusion

If a baby is breastfed and bottlefed in the same way, they may have nipple confusion. Here are signs that your baby may have nipple confusion:

  • Your baby thrusts his tongue upwards while sucking. This movement can cause your baby to push the nipple out of his mouth.
  • Your baby doesn’t open his mouth wide enough. If your baby doesn’t open his mouth wide enough, he will not get enough milk from the latch, and the mother’s nipples will be very sore as a result.
  • Increased fussiness. If mother’s milk isn’t instantly available because your baby has nipple confusion, then this will cause a delay in the let-down reflex from the milk.

How to Avoid Nipple Confusion

It’s best not to use bottles and pacifiers until the nursing is going well. (Although, it’s no catastrophe if your baby gets a pacifier a few times in the hospital.) Once your baby has the hang of nursing, I recommend giving one bottle feeding per day (preferably of breast milk or—if you don’t have enough milk pumped—breast plus some warm water that you previously boiled. But don’t dilute the milk more than once a day. Frequent watered-down feedings are bad for her health.) This way, your baby will learn how to take a bottle from another caregiver, in case you get sick, become unavailable, or have to return to work.

How to Fix Nipple Confusion

You can work on reversing nipple confusion by increasing your low milk supply in order to spend more breastfeeding time with your baby. 

When to Introduce a Bottle?

When to introduce a bottle to a breastfed baby? If you wait longer than 4 weeks to introduce the bottle to a baby, you may be rudely surprised by your baby’s emphatic rejection of the rubber nipple! Once you start bottles, try not to skip more than one or two days without giving one. (Some babies stubbornly refuse the bottle if their moms take too long a break.)
