Baby Gas & Colic: A Mom's Guide to Relief & Survival

My first baby had colic. I know this because every evening from 6 PM to 10 PM, he would scream, pull his legs up to his chest, turn bright red, and nothing—nothing—would soothe him. I walked miles with him in the carrier, bounced on an exercise ball until my legs ached, tried every gas drop and gripe water on the market, and cried right along with him on more than one night. If your baby is going through this, I want you to know: it gets better. And there are things that actually help. Here's what I learned the hard way.

Is it gas, colic, or something else?

These terms get used interchangeably, but they're different:

Gas is simply trapped air in the digestive tract. All babies have gas—their immature digestive systems are still learning to process food, and they swallow a lot of air while feeding and crying. Gas can cause discomfort, bloating, fussiness, and pulling legs up. Most baby gas is normal and not a sign of anything wrong.

Colic is defined by the "Rule of Three": crying for more than 3 hours per day, more than 3 days per week, for more than 3 weeks, in an otherwise healthy, well-fed baby. Colic typically starts around 2-3 weeks, peaks at 6-8 weeks, and resolves by 3-4 months. The crying usually happens in the evening (the "witching hour") and is intense—high-pitched, inconsolable, with the baby pulling legs up, clenching fists, and arching the back.

Reflux (GERD) is when stomach acid flows back up the esophagus, causing pain and discomfort. Signs include arching the back during/after feeding, spitting up forcefully (projectile vomiting), crying during feeding, refusing to eat, poor weight gain, and a sour breath smell. Reflux is different from normal "happy spitter" spit-up—if your baby spits up but is happy and gaining weight, that's normal reflux (GER), not GERD.

Food allergy or intolerance (especially cow's milk protein allergy) can cause gas, fussiness, bloody stools, vomiting, eczema, and poor weight gain. If you suspect a food allergy, talk to your pediatrician.

The key distinction: if your baby is otherwise healthy—gaining weight well, eating normally, happy between crying episodes, no fever or other symptoms—the crying is likely colic or normal baby gas. If there are other concerning symptoms, check with your pediatrician.

What causes baby gas and colic?

Gas causes:

• Swallowing air while feeding (especially with a fast let-down, improper latch, or bottle nipple that's too fast)
• Crying (babies swallow a lot of air when they cry, which creates a vicious cycle—gas causes crying, crying causes more gas)
• Immature digestive system (babies' guts are still developing the enzymes needed to fully digest milk)
• For breastfed babies: gassy foods in mom's diet (dairy, caffeine, cruciferous vegetables like broccoli/cauliflower/cabbage, beans, onions, garlic, spicy foods)—though the evidence for this is mixed and varies by baby
• For formula-fed babies: certain formula types, improper mixing (too much air from shaking), or a nipple that lets in too much air
• Constipation (trapped stool can block gas from passing)

Colic causes: The exact cause of colic is still unknown, but leading theories include: gastrointestinal discomfort (gas, reflux, immature digestion), overstimulation (babies can become overwhelmed by the world and need to "release" through crying), neurological immaturity (the nervous system is still regulating itself), and temperament differences (some babies are simply more sensitive and intense). Colic is NOT caused by bad parenting, a spoiled baby, or something you did wrong.

What actually works to relieve baby gas?

Here are the techniques that worked for me, in order of effectiveness:

1. Burp effectively (and often)

Don't wait until the end of the feed to burp. Burp mid-feed (every 2-3 oz for bottle-fed, or when switching breasts for breastfed) and after the feed. Try different burping positions: over the shoulder (pat or rub the back in an upward motion), sitting on your lap (support the chin/chest with one hand, pat the back with the other), or lying across your knees ( tummy-down across your lap, pat the back). I found the "sitting on lap" position worked best for my gassy baby—lean him slightly forward, support his chest and chin, and pat firmly but gently.

2. Bicycle legs

Lay your baby on their back, hold their ankles, and gently move their legs in a bicycle motion. This puts gentle pressure on the abdomen and helps move trapped gas through the intestines. I did this during every diaper change when my baby was gassy, and it often produced an immediate toot (and a much happier baby). You can also gently press their knees up toward their chest and hold for 5-10 seconds, then release—repeat a few times.

3. Tummy massage

Using warm hands (rub them together first), gently massage your baby's belly in a clockwise circular motion, starting at the navel and moving outward. You can also do "I Love U" strokes: trace an "I" on the left side, an upside-down "L" across the top and down the left, and a "U" around the perimeter. Keep it gentle—you're stimulating the intestines, not pushing hard. I paired this with bicycle legs for a one-two punch.

4. Warm compress

A warm (not hot!) washcloth on the belly can relax the abdominal muscles and help gas pass. I would warm a washcloth under the tap, test the temperature on my wrist (should be comfortably warm, not hot), and lay it on my baby's belly for a few minutes while I did bicycle legs. You can also lay your baby tummy-down across your warm lap (skin-to-skin if possible).

5. Tummy time

Putting your baby on their tummy (while awake and supervised) puts gentle pressure on the abdomen and helps move gas. It also strengthens neck and shoulder muscles. Start with short sessions (2-3 minutes) and gradually increase. I did tummy time after feeds (wait 20-30 minutes to avoid spit-up) and it often helped release trapped gas.

6. Feeding adjustments

For breastfed babies: check the latch (a poor latch causes air swallowing), try a laid-back feeding position, and slow down a fast let-down (express a little milk before latching, or use a nipple shield if recommended). For bottle-fed babies: use an anti-colic bottle with a vent system, make sure the nipple is the right flow (too fast = gulping air), keep the bottle tilted so the nipple is always full of milk (no air in the nipple), and stir formula instead of shaking (shaking creates bubbles—stirring reduces air). I switched to anti-colic bottles and noticed a real difference in my bottle-fed baby's gas.

7. Infant gas drops (simethicone)

Simethicone (brand names like Mylicon, Little Remedies) works by breaking up gas bubbles in the stomach. It's generally considered safe for infants and doesn't get absorbed into the bloodstream. I found it helpful for my baby when given before feeds, though the evidence is mixed—some studies show it's no better than placebo. It's worth trying since it's low-risk. Follow the dosage on the package based on your baby's weight.

8. Gripe water

Gripe water is a herbal supplement (usually containing fennel, ginger, chamomile, and/or sodium bicarbonate) marketed for gas and colic. The evidence for gripe water is limited and inconsistent. Some parents swear by it; others see no difference. If you try it, choose a brand without alcohol, sugar, or artificial colors, and check with your pediatrician first. I tried several brands and didn't notice a consistent effect, but every baby is different.

How to survive the colic "witching hour"

If your baby has colic, the evening crying sessions are the hardest. Here's what got me through:

• Wear your baby. A carrier or sling keeps your baby close, warm, and moving. The motion and your heartbeat can be soothing. I wore my colicky baby in a wrap for hours every evening—he'd often fall asleep on me even if he'd been screaming minutes before.
• White noise. A white noise machine, fan, or even a hairdryer/vacuum cleaner sound can mimic the womb environment and soothe a crying baby. I used a white noise app on my phone at a low volume.
• Motion. Rocking, bouncing, walking, swinging, going for a car ride—motion is one of the most effective colic soothers. I bounced on an exercise ball while holding my baby, and the rhythmic up-and-down motion often calmed him.
• Swaddle. A tight swaddle recreates the womb feeling and prevents the startle reflex from waking/crying. Make sure the swaddle is safe (hips can flex, no loose fabric near the face). Stop swaddling once your baby shows signs of rolling over.
• Skin-to-skin. Taking off your baby's clothes (diaper only) and holding them against your bare chest regulates their temperature, heart rate, and stress hormones. I did this during evening crying sessions and it often helped.
• Take breaks. This is the most important tip for YOUR sanity. If you're feeling overwhelmed, put your baby in a safe place (crib, playpen) and step away for 5 minutes. Take deep breaths, drink water, call a friend. A crying baby in a safe crib is fine for 5 minutes while you reset. NEVER shake a baby—if you feel yourself losing control, put the baby down and walk away.
• Share the load. If you have a partner, family member, or friend who can take a shift, let them. Colic is exhausting, and you can't pour from an empty cup. My husband took the 8-10 PM shift so I could eat dinner and shower, and that made all the difference.

When should I call the pediatrician?

Call your pediatrician if your baby has any of these alongside the crying/gas:

• Fever (rectal temperature 100.4°F/38°C or higher in babies under 3 months)
• Refusing to eat or poor weight gain
• Projectile vomiting (forceful, shooting across the room)
• Blood in stool or vomit
• Severe abdominal distension (hard, swollen belly that's tender to touch)
• Lethargy, weakness, or difficulty waking
• Breathing difficulties or blue lips
• Crying that is constant and cannot be comforted at all (not just evening episodes)
• Diarrhea or constipation that persists
• Signs of dehydration (fewer than 6 wet diapers per day, dry mouth, sunken fontanelle)

Also call if you're feeling overwhelmed, depressed, or unable to cope. Postpartum depression and anxiety are common, and colic can make them worse. Asking for help is the best thing you can do for yourself and your baby.

Article Summary

Baby gas is normal—caused by swallowing air, immature digestion, and feeding issues. Colic is defined by the Rule of Three (3+ hours/day, 3+ days/week, 3+ weeks) and typically starts at 2-3 weeks, peaks at 6-8 weeks, and resolves by 3-4 months. Effective gas relief techniques include: burping effectively and often, bicycle legs, tummy massage (clockwise circles), warm compresses, tummy time, feeding adjustments (anti-colic bottles, proper latch, slow nipple flow), infant gas drops (simethicone), and gripe water (evidence mixed). For colic, the "witching hour" can be survived with babywearing, white noise, motion (rocking/bouncing/car rides), swaddling, skin-to-skin contact, taking breaks, and sharing the load with a partner. Call the pediatrician if there's fever, poor weight gain, projectile vomiting, blood in stool/vomit, severe abdominal distension, lethargy, breathing difficulties, or constant inconsolable crying. Most importantly: colic is temporary. It ends. You are not a bad parent, and your baby is not broken—this is a phase, and it will pass.

Frequently Asked Questions

When should I call the pediatrician?

Call your pediatrician if your baby has a fever over 100.4°F (38°C) under 3 months old, seems lethargic or difficult to wake, refuses to eat or drink, has persistent vomiting or diarrhea, shows signs of dehydration (fewer wet diapers, dry mouth, sunken fontanelle), has difficulty breathing, or if something just doesn't seem right. Trust your instincts as a parent.

How can I tell if my baby is in pain?

Babies show pain through crying that's different from their usual cry — it may be higher-pitched, more intense, or difficult to soothe. Other signs include facial grimacing, clenched fists, drawing legs up to the chest, changes in sleep or feeding patterns, and being unusually fussy or unusually quiet. If you suspect pain, check for common causes like teething, gas, ear infection, or injury.

Is it normal for my baby to get sick often?

It's normal for babies and toddlers to get 6-8 colds a year, especially if they're in daycare or around older siblings. Their immune systems are still developing and building immunity. However, frequent infections that are severe, last a long time, or are accompanied by poor weight gain may warrant a checkup with your pediatrician to rule out underlying issues.

How do I give my baby medicine safely?

Always use the measuring device that comes with the medicine — never use a household spoon. Check the dose based on your baby's weight, not just age. Give the full prescribed course of antibiotics even if your baby seems better. Never give aspirin to children under 18, and check with your pediatrician or pharmacist before combining medicines or giving over-the-counter medicine to babies under 6 months.
