Is nipple shields for breastfeeding safe?

Assigned clinical reviewerSharyn Harrison· CNM, NPDraft · pending clinical reviewUpdated

What does the evidence say about nipple shields for breastfeeding while breastfeeding?

  1. A 2026 randomized trial of 660 mothers with nipple abnormalities found higher exclusive breastfeeding with shields at two and three months, but no difference at six months and lower crude overall breastfeeding continuation at six months. Growth after discharge was not measured. 1
  2. In a within-subject study, shields did not significantly change milk transfer among 25 dyads already using them for nipple pain, but applying a shield to 34 control dyads without breastfeeding problems reduced transfer. The device effect depended on the population and indication. 2
  3. A mechanistic pumping study found lower percentage milk removal with a fitted shield in its adjusted analysis, although only 11 paired sessions met the preset vacuum-validity criteria. The authors advised close clinical monitoring rather than assuming transfer is adequate. 3
  4. A review of 14 studies found shields were commonly used for flat nipples or early latch failure and described mixed milk-transfer and breastfeeding outcomes across older and newer designs. It supports targeted use with skilled follow-up, not routine use for every painful feed. 4
  5. A prospective nonrandomized study of 54 term-infant dyads found no statistically significant weight-gain difference through two months between shield and non-shield feeding. Formula use and nonrandom assignment limit reassurance for exclusive milk transfer in every dyad. 5

How nipple shields for breastfeeding changes by nursing stage

  • Early weeks. use a shield only after someone observes a full feed and checks why latch or pain is difficult. Confirm that the infant takes more than the shield tip, milk is heard or seen transferring, and weight and diaper output are followed.
  • Established nursing. reassess whether the shield still improves transfer or comfort. If feeds remain long, the breast never softens, pumping output falls, or growth slows, a lactation and pediatric review can check fit, latch, oral function, and milk supply.
  • Weaning. there is no fixed deadline. Try direct latching when both parent and infant are calm, but do not remove a useful shield abruptly if intake falls. A planned transition uses observed feeds and growth rather than success on one feed alone.

Frequently asked questions

What is a nipple shield used for?

A nipple shield is a thin device placed over the nipple and areola during a feed. It may help a selected infant attach when there is a short or flat nipple, early latch failure, prematurity-related feeding difficulty, or persistent pain, but the underlying cause still needs assessment.

How should a nipple shield fit?

A fitted nipple shield should draw the nipple comfortably into the tunnel without rubbing or pinching. The infant should latch deeply over the shield and breast, not suck only on the tip. Fit is best checked during an observed feed because breast and infant anatomy both matter.

Can a nipple shield reduce milk transfer?

Yes, it can in some settings, but not every dyad responds the same way. Experimental pumping data found reduced milk removal, while a feeding study found no significant transfer change among mothers already using shields for pain. Monitor the infant and milk supply rather than assuming either outcome.

How can I tell whether my baby gets enough milk through a shield?

Look for rhythmic swallowing, breast softening, age-appropriate wet and soiled diapers, satisfaction after feeds, and steady weight gain. A weighted observed feed can answer a specific transfer question. Pump volume alone cannot establish what the infant removes at the breast.

Will a nipple shield fix breastfeeding pain?

Not reliably. In one within-subject study, pain scores among shield users were similar with and without the device. Pain can reflect shallow latch, nipple trauma, vasospasm, infection, pump injury, or infant oral issues, so a shield should not delay finding the cause.

Can nipple shields affect milk supply?

Supply can fall if the shield or latch reduces milk removal over repeated feeds. It may remain adequate when transfer is effective. Follow breast fullness, swallowing, diapers, infant weight, and any need for pumping or supplementation with a lactation professional rather than adding pumping automatically for everyone.

How long should I use a nipple shield?

There is no evidence-based universal number of days. The 2026 trial supports shields as a temporary targeted aid with follow-up, and earlier studies included much longer use. Continue only while it solves a defined problem and intake and growth remain adequate.

How do I stop using a nipple shield?

Try direct latching when the infant is calm or after milk begins flowing, and get help if transfer drops. A gradual transition can alternate shield and direct feeds. The goal is not speed. It is comfortable feeding with adequate intake and a stable milk supply.
