## TLDR

- A sudden refusal in a baby who nursed well is usually a strike, not weaning, and most last 2-5 days.
- Keep the baby fed with expressed milk or formula, pump to protect supply, and offer the breast when drowsy or in a warm bath.
- See an IBCLC if it lasts beyond a few days, and the pediatrician for fever, ear pulling or fewer wet diapers.

## Strike or weaning?

A nursing strike is a sudden refusal of the breast in a baby who was nursing well, usually after
about 3 months. The baby may arch, cry and push away, yet still seem hungry. Babies rarely wean on
their own before 12 months, and self-weaning happens slowly, not overnight. Most strikes last 2-5
days, sometimes longer.

## Common triggers

- Pain: teething, an ear infection, a sore mouth or thrush.
- A blocked nose that makes it hard to breathe while nursing.
- A bite followed by a startled reaction from the parent.
- Distraction at 4-6 months, when the world gets interesting.
- A change in milk flow or taste: lower supply, a period, a new pregnancy.
- A new soap, lotion or perfume, or stress, travel or a change in routine.
- Lots of bottles with fast flow.

## Getting back to the breast

- Keep the baby fed: offer pumped milk or formula by cup, spoon or paced bottle while you work on it.
- Pump or hand express whenever the baby would usually nurse, to protect supply.
- Offer the breast when the baby is drowsy, just waking, or in a warm bath together.
- Try lots of skin-to-skin without pressure to nurse.
- Nurse while walking, rocking or swaying, or in a dark, quiet room.
- Try a different position, including laid-back or one where the baby is more upright.
- Don't force or hold the baby to the breast. Stop if they get upset and try later.
- Treat what's treatable: saline and suction for a stuffy nose, a pediatrician visit for ear pain.

## Biting

Calmly unlatch with a finger in the corner of the mouth and pause the feed briefly. Watch for the
end of active sucking, when bites usually happen, and offer a teether before feeds.

## Bottle refusal in a breastfed baby

The combination feeding guide covers basic bottle tips. If those haven't worked:
- Have the bottle given by someone else, with the nursing parent out of the house.
- Try at a sleepy, calm time, not when the baby is very hungry.
- Change one thing at a time over several days: nipple shape, milk temperature, position.
- From about 6 months, skip the bottle: an open cup or straw cup works for many babies.
- Babies in childcare often drink less and reverse cycle, nursing more at night and evenings.
  That's normal if the baby is growing and has wet diapers.

## Bottle-fed babies who refuse

Look for a cause: nipple flow too fast or slow, illness, teething, or a pressured feeding routine.
Let the baby lead the pace and stop when they turn away.

## When to check in

- See an IBCLC if a strike lasts beyond a few days or supply is dropping.
- See the pediatrician if refusal comes with fever, ear pulling, mouth sores, or wet diapers
  dropping below about 4-6 a day.
