Your newborn cries at the breast, or settles to nurse and then cries the minute the feed ends. It is one of the most common worries new parents bring to us, and the answer is usually simple: something about the feed is making your baby uncomfortable. Here is how to tell what is going on during and after feeds, what helps, and when to call your doctor.
| What you notice | Likely cause | Try this |
|---|---|---|
| Squirming, pulling legs up, a hard belly | Gas | Burp more often, bicycle legs |
| Spitting up, arching, fussing mid-feed | Reflux | Smaller feeds, keep upright after |
| Gulping, coughing, pulling off the breast | Fast letdown | Laid-back nursing, unlatch at letdown |
| Rooting and sucking hands right after | Still hungry | Offer the other side, check latch |
| Fussing and tugging at the breast mid-feed | Slow flow | Breast compressions, switch sides |
| Rubbing eyes, looking away, crying at night | Overtired | Dim the room, swaddle, rock |
Why your baby cries after feeding
Gas and swallowed air
Babies swallow air while they eat, especially with a shallow latch, a fast-flowing bottle, or when they are gulping because they are very hungry. That trapped air is uncomfortable, and it can also bring on baby hiccups.
- Burp when you switch sides, or every 2 to 3 ounces from a bottle, not only at the end.
- Hold your baby upright against your shoulder and pat or rub from the lower back up toward the shoulders.
- Check the latch. A wide, deep latch lets in less air. Our guide to breastfeeding positions can help.
- Try gentle bicycle legs or tummy time while awake to help move gas along.
Acid reflux and spitting up
Acid reflux happens when milk comes back up from the stomach into the esophagus. It is very common: more than half of babies spit up in their first months. It usually peaks around 4 months and goes away on its own between 12 and 18 months.
Signs of reflux include:
- Spitting up or vomiting after feeds
- Fussing, arching, or pulling away during a feed
- Wet burps or hiccups
- Coughing, gagging, or choking
- Disturbed sleep
Smaller, more frequent feeds and keeping your baby upright for 15 to 20 minutes afterward often help. Most reflux is harmless. When it comes with poor weight gain, refusing to eat, or forceful vomiting, it may be gastroesophageal reflux disease (GERD), which needs a pediatrician’s care.
A fast letdown or oversupply
If your milk sprays out quickly, your baby may gulp, cough, click, or pop off the breast, then swallow extra air and cry afterward. Nursing in a laid-back, reclined position lets your baby control the flow. You can also unlatch for a moment when your milk lets down, catch the spray in a cloth, and latch again once it slows.
Still hungry
Sometimes the crying means your baby wants more. Growth spurts and cluster feeding in the evening are normal. Watch for hunger cues like rooting, lip smacking, and sucking on hands, and offer the other breast. If your baby often seems hungry after long feeds, or is not gaining well, ask your pediatrician or a lactation consultant to check how much milk your baby is getting.
Food sensitivity or milk protein allergy
A small number of breastfed babies react to proteins from foods in their mother’s diet. Cow’s milk protein is the most common one, and egg, soy, and corn come up too. Signs include extreme fussiness after feeds, eczema, vomiting, and mucus or blood in the stool.
If you see these signs, talk with your pediatrician before you change your diet. If they suggest cutting a food out, remove one at a time and give it a few weeks, so you can see what actually makes a difference.
Formula that does not agree
For formula-fed babies, a switch of formula is sometimes the fix. Every formula affects babies a little differently, so ask your pediatrician which option to try. If one switch makes no difference, more switching is unlikely to help, and it is worth looking at the other causes here.
Colic
Colic is persistent, intense crying in a healthy, well-fed baby. Doctors often use the rule of threes: crying for more than 3 hours a day, at least 3 days a week, for 3 weeks or more. It often starts in the first few weeks, is worst around 6 weeks, and usually gets better by 3 to 4 months. Nobody knows exactly what causes it, and it is not your fault.
Tired or overstimulated
A full tummy makes babies sleepy, and a sleepy baby who cannot settle will cry. Bright lights, noise, and lots of handling can push a newborn past the point of calm. Feed in a quiet spot and move straight into a calm wind-down.
Why your newborn cries during feeding
Crying while nursing or taking a bottle has its own short list of causes. Watch when in the feed it starts, because that is usually the clue.
The milk comes too fast
If your baby cries, coughs, or pulls off a minute or two into a feed, your letdown may be strong. The same thing happens with a bottle nipple that flows too fast. Try a laid-back position at the breast, or a slower-flow nipple and paced bottle feeding with pumped milk.
The milk comes too slowly
A baby who fusses, tugs, or pops on and off later in the feed may be frustrated that the flow has slowed. Gently squeezing your breast while your baby sucks (breast compressions) keeps milk moving, and switching to the other side can help. If this happens at most feeds, a lactation consultant can check your supply and how well your baby is transferring milk.
The latch is shallow or uncomfortable
A shallow latch lets in air and makes it harder for your baby to get milk, which is frustrating for both of you. Clicking sounds, a sore or creased nipple after feeds, and short, choppy sucks are signs to work on the latch. Sometimes a tongue tie is part of it, which a pediatrician or IBCLC can check.
Gas or reflux mid-feed
Swallowed air can build up before the feed is done. If your baby squirms, arches, or pulls away partway through, pause for a burp and then carry on. Babies with reflux often fuss and arch during feeds as well as after.
A stuffy nose or sore mouth
Babies breathe through their nose while they feed, so a cold can make nursing hard and upsetting. White patches inside the mouth that do not wipe away can be thrush, which makes sucking sore. Both are worth a call to your pediatrician.
Should you breastfeed every time your baby cries?
Not always. Crying is a late hunger sign, so it is best to feed when you see early cues, before the tears start. But if your baby just had a full feed and is crying again, look at the other causes first: gas, a wet diaper, being too warm or cold, or simply needing to be held.
Feeding on demand is still the right approach, and comfort nursing is fine if it settles your baby. Let your baby decide when they have had enough. A baby who is done will slow down, let go, turn away, or fall asleep.
How do I comfort a crying newborn?
- Hold them close. Skin-to-skin contact, cuddling, or a snug swaddle helps babies feel safe.
- Rock or sway. Gentle, rhythmic motion calms most newborns.
- Offer a pacifier. Sucking is soothing on its own, without more milk.
- Make some noise. Shushing, soft singing, or white noise sounds like the womb.
- Go for a walk. A stroller ride or a walk around the house can reset the mood.
If you are exhausted and the crying will not stop, it is okay to lay your baby on their back in a safe crib and take a few minutes to breathe. Asking a partner, friend, or family member to take a turn is a good idea, not a failure.
Knowing why your baby cries during or after feeding takes a lot of the worry out of it. Most of the time it is gas, reflux, the flow of milk, or a tired baby, and small changes help. If you are pumping or bottle feeding, a good breast pump makes it easier: we work with plans including UPMC, TRICARE, Aetna, and many others.
Questions parents ask about crying after feeds
My one-month-old won’t stop crying after breastfeeding. What should I do?
Crying tends to build in the first weeks and is often worst around 6 weeks, so you are not imagining it. Burp during and after the feed, hold your baby upright for 15 to 20 minutes, and watch for a fast letdown. Check that your baby has at least 6 wet diapers a day and is gaining weight. If your baby cries for hours most days, it may be colic. Call your pediatrician if there is a fever, vomiting, fewer wet diapers, or you are worried. That is always a good enough reason.
Why does my newborn cry while breastfeeding?
Usually because the milk is flowing too fast or too slowly, the latch is shallow, or your baby needs to burp mid-feed. Notice when in the feed the crying starts: early often points to a fast letdown, later to a slower flow.
Is it normal for a newborn to cry after every feeding?
Fussing after some feeds is common, usually from gas or reflux. If your baby cries after nearly every feed, seems in pain, or is not gaining weight, check in with your pediatrician.
Can what I eat make my breastfed baby fussy?
Sometimes. Cow’s milk protein is the most common trigger, followed by foods like egg and soy. Talk with your pediatrician before you cut anything out, and remove one food at a time so you can see what helps.
How can I tell if my baby is overfed?
Overfed babies often spit up a lot, seem gassy and uncomfortable, and cry after feeds. With bottles, try paced feeding: hold the bottle more level, pause often, and let your baby set the pace.
Why does my baby cry after feeding but still seem hungry?
It may be a growth spurt or cluster feeding, which is normal. If it happens often, a lactation consultant can check your latch and how much milk your baby is getting.
When does crying after feeding get better?
For most babies, gas and colic ease by 3 to 4 months, and reflux usually goes away by 12 to 18 months as the digestive system matures.
