Newborn crying can feel urgent and confusing, especially when it spikes in the evening and nothing seems to help. Two common culprits—baby gas and colic—can look similar at first, but the patterns, timing, and response to soothing often differ. This guide breaks down practical ways to tell them apart, reduce discomfort, and know when to call the pediatrician.
Gas and colic often overlap in the way they look from the outside: intense crying, a red face, and a tense little body that can worry any caregiver. Gas discomfort tends to come and go and may improve after burping, passing stool, or passing gas. Colic, on the other hand, is commonly described as frequent, prolonged crying in an otherwise healthy baby—often peaking around 6–8 weeks and easing by 3–4 months.
Part of the confusion is developmental. Newborn digestive systems are still maturing, and feeding, swallowing air, and normal gut movement can amplify fussiness. That means a baby can have some gassiness while also having a predictable “cry window,” so it helps to look for patterns instead of one single symptom.
Timing, duration, and whether typical soothing works are usually the clearest clues. If you’re unsure, track crying in a simple log for 3–5 days: time of day, feeding method, stool, spit-up, and what helped. Even a short record can reveal whether episodes cluster after feeds (more gas-like) or show up at a consistent time no matter what (more colic-like).
| Clue | More consistent with gas | More consistent with colic |
|---|---|---|
| Timing | Often shortly after feeding; may coincide with burping needs or bowel movements | Often occurs at similar times daily (commonly evenings), even with “good” feeds |
| Duration | Usually shorter episodes; improves after burping, bicycle legs, or passing gas | Prolonged crying (can be 3+ hours/day, several days/week) with hard-to-console stretches |
| Baby’s body cues | Squirming, drawing knees up, grunting; relief after gas passes | Tense body, clenched fists, arched back; may not settle with typical comfort steps |
| Feeding connection | More likely linked to fast letdown, bottle flow, poor latch, or swallowed air | Not always linked to technique; may persist despite careful feeding routines |
| Between episodes | Often comfortable and calm | Can be calm between episodes, but caregivers often note a predictable daily “witching hour” |
Gas discomfort commonly shows up as frequent pulling of legs toward the belly, grunting, and sudden crying that improves with burping or passing gas. Some babies also gulp during feeds or spit up more when they’re taking in extra air.
Common triggers include fast milk flow (breast or bottle), a shallow latch, skipping paced bottle-feeding, overfeeding, or long gaps between feeds that lead to frantic, air-swallowing feeding. Some babies are also simply more sensitive to normal intestinal movement—still manageable with routine, positioning, and calmer feeds.
Colic often looks like intense, prolonged crying that’s hard to soothe and tends to happen at predictable times of day. The baby may appear to be in pain but continues to feed and grow normally and has a normal exam.
Colic isn’t caused by “bad parenting,” and it’s not a sign your baby will have a difficult temperament later. Still, because prolonged crying can overlap with medical issues, it’s important to check for red flags rather than assuming it’s colic. Helpful background reading can be found from the American Academy of Pediatrics.
For bottles, slow the flow and use paced bottle-feeding with frequent pauses. Make sure the bottle is angled so the nipple stays filled with milk to minimize air. If nipples are worn and dripping too fast, replace them. For additional remedies and burping positions, see Mayo Clinic’s infant gas overview.
If you feel overwhelmed, place your baby on their back in a safe sleep space for a few minutes and take a breather. Ask for help early—prolonged crying is stressful, and support is part of safe care. For more general guidance on colic, the NHS colic page offers a practical overview.
Gassiness is common in the early months as digestion matures. Many babies improve noticeably by 3–4 months, especially when feeding technique, burping, and upright time after feeds are consistent.
Normal evening fussiness is usually shorter and more consolable, while colic tends to be prolonged and difficult to soothe in a predictable pattern. A common clinical framing is crying for 3 or more hours a day, 3 or more days a week, but a clinician should confirm the diagnosis.
It can be urgent if there’s fever in a young infant, breathing trouble, extreme sleepiness, signs of dehydration, green (bilious) vomiting, blood in stool, or inconsolable crying with concerns for injury or swelling. If any of these are present, contact urgent care or emergency services right away.
