What to Do If Your Baby Refuses the Breast

Medically reviewed by pediatrician and perinatal psychologist Polina Kizino

When a baby refuses the breast, it can be upsetting — but it’s usually temporary. The reasons may vary: a stuffy nose, a change in surroundings, or stress. Try offering the breast when your baby is sleepy — before naps or just after waking. Cuddle often and breastfeed in a calm setting. This isn’t a reason to stop breastfeeding if you wish to continue. Talk to your doctor — with support, things can often be brought back on track.

What’s Inside

Quick takeaways

  • Temporary breast refusal is common and doesn’t mean breastfeeding must end.
  • Causes may be physical (like nasal congestion or mouth pain) or emotional. A tongue-tie may also be the reason — though in that case, refusal is usually ongoing.
  • Skin-to-skin contact, calmness, and trying to nurse while the baby is drowsy may help.
  • Sometimes, refusal signals that the baby isn’t getting enough milk — consult your doctor if you’re unsure.
  • Breastfeeding can usually be restored — with patience, support, and small steps.

Why a baby may refuse the breast

Doctors call this a “nursing strike” — and it’s usually temporary. Possible reasons include:

  • Teething, thrush, or other mouth pain
  • Stuffy nose — baby struggles to breathe while nursing
  • New scent on mom (perfume, deodorant), or a change in milk flavor (due to ovulation, new foods, or medications)
  • Overfull breast (too fast flow) or low milk flow
  • Stress in baby or mom (e.g., after vaccines or travel)
  • Brief separation or mom’s startled reaction to biting can also trigger refusal

How to help your baby return to breastfeeding

Stay calm, gentle, and close — most strikes last from a few hours to a couple of days.

What may help:

  • Skin-to-skin contact — cuddle with your baby unclothed, covered with a light blanket
  • Try feeding when sleepy — many babies nurse better while falling asleep or just waking
  • Dim lights and reduce noise — calm, quiet environments help
  • Gently offer the breast — don’t force, but give regular opportunities
  • Avoid new changes — don’t introduce bottles, solids, or major transitions during a strike
  • If the nose is blocked, decongestant drops can be used briefly, but only under medical guidance

How to know if it’s more than just behavior

Sometimes refusal signals lactation issues. Contact your doctor or lactation consultant if you notice:

  • Less than 6 wet diapers after day 4
  • Refusal to eat along with lethargy or weight loss
  • No audible swallowing while nursing
  • No breast fullness or letdown sensation in mom
  • Nipple pain, cracks, or intense discomfort during feeding

Timely support may include temporary supplementation with expressed milk or formula.

Important: if supplementation is needed

If the doctor recommends supplementation, it doesn’t mean breastfeeding must stop:

  • Use a bottle, a syringe or a supplemental nursing system (as advised)
  • Keep offering the breast
  • Express milk to maintain supply
  • Gradually return to full breastfeeding as things improve
  • Some babies also benefit from breast milk fortifiers, especially with low weight — prescribed by the doctor

Frequently Asked Questions About Breast Refusal

Why is my baby suddenly refusing the breast?

A nursing strike can happen at any age and is usually temporary. Common reasons include a stuffy nose, teething, mouth discomfort, changes in milk flow, stress, new smells, or changes in routine.

How can I encourage my baby to breastfeed again?

Try offering the breast when your baby is sleepy, such as before a nap or just after waking. Skin-to-skin contact, a quiet environment, and gentle, pressure-free attempts can help rebuild interest in nursing.

How long does a nursing strike usually last?

Most nursing strikes last from a few hours to a couple of days. Continuing to offer the breast calmly and maintaining close physical contact often helps babies return to breastfeeding.

When should I contact a doctor about breast refusal?

Seek medical advice if breast refusal is accompanied by fewer wet diapers, lethargy, weight loss, lack of audible swallowing, nipple pain, or concerns about milk supply. These signs may indicate feeding or lactation problems that need support.
