How can you tell if your baby has gas?

Read the UK edition

The short answer

Babies may swallow air while feeding or crying, and may burp, pass gas, briefly squirm or draw up their legs. These signs are not specific to gas, and frequent crying does not prove that gas is the cause. Crying can also lead to swallowed air, so consider feeding, comfortable periods and warning signs together.

Keep in mind

  • Passing gas often is not a problem by itself; feeding, comfort between episodes and overall wellbeing matter.
  • Gas and colic are not the same, and evidence does not strongly support gas drops or gripe water for colic crying.
  • Do not place a baby on their stomach or on an incline to sleep for gas or reflux; use a clear, flat sleep surface and place them on their back.

Why is gas so common in babies?

Babies swallow air while nursing, bottle-feeding and crying; digestion also naturally produces gas. They release it by burping or passing wind, so frequent gas can be an ordinary part of digestion.

Drawing up the legs, facial redness and squirming can occur with gas, but also with bowel movements, tiredness and ordinary newborn movements. One behavior cannot identify the cause.

Can gas cause crying, or can crying cause gas?

Either may happen. Trapped air can make a baby uncomfortable, while prolonged crying can lead to more swallowed air and later gas. Settling after passing wind does not prove that gas caused all the crying.

Labelling every cry as gas can distract from hunger, tiredness, overstimulation, illness or a need for contact. Check basic needs and how your baby is acting overall.

Can feeding technique affect swallowed air?

With a bottle, very fast flow, an unsuitable teat or bottle angle can make sucking, swallowing and breathing harder to coordinate. A shallow latch, repeatedly coming off the breast or a forceful milk flow may also coincide with swallowed air.

If discomfort repeatedly follows feeds, review latch, position and flow rather than trying products at random. If your baby is comfortable and feeding well, you do not need to make them burp for a long time after every feed.

What can you try if your baby seems uncomfortable?

If your baby becomes unsettled during a feed, pause briefly, support their head and neck, hold them upright and gently rub their back. When awake, gentle bicycle-leg movements, light tummy contact or supervised tummy time may comfort some babies.

Avoid tummy time immediately after a feed if it seems to worsen spit-up. Whenever your baby sleeps, place them on their back on a firm, flat, empty sleep surface.

Are gas drops, diet changes or a different formula needed?

There is no strong evidence that simethicone or herbal gripe water reduces colic crying. Ingredients and dose safety vary by product, so do not treat these as routine remedies.

Do not cut dairy, pulses or vegetables from a breastfeeding parent’s diet, or frequently switch formula, just because of gas. If allergy or feeding symptoms raise concern, plan any change with a health professional.

Which signs should not be dismissed as gas?

With common developmental gas, a baby is often comfortable, alert and able to feed between episodes. Worsening persistent crying, a clearly hard or swollen abdomen, green or bloody vomit, or blood in the stool is not ordinary gas behavior.

If your baby has a fever, refuses feeds, has fewer wet diapers, is difficult to wake or unusually lethargic, do not keep trying gas techniques; seek medical assessment, especially for a young infant.

What can you do during the next unsettled spell?

Note whether the discomfort starts during a feed, just afterwards or after a longer period of crying.

Check feeding position and flow, pause briefly for a burp, and try one gentle comfort measure while your baby is awake.

Consider how your baby is between episodes, along with feeding, diapers and any warning signs.

When to seek support

Some signs need emergency help; other concerns can be discussed with your child’s healthcare team.

  • A clearly hard or swollen abdomen, green or bloody vomit, blood in the stool, or inability to pass stool or gas.
  • Fever, refusal to feed, fewer wet diapers, difficulty waking or marked lethargy.
  • Increasing, unusually high-pitched or inconsolable crying, especially if your baby also seems unwell between episodes.
