Caring for a newborn comes with joy—and sometimes a lot of crying. If your baby is crying for long stretches, especially in the evening, and seems gassy or hard to soothe, they may be experiencing colic.

As a lactation consultant, I often support families navigating these difficult early weeks. This guide breaks down what colic is, why it happens, and what you can do to comfort your baby and reduce gassiness—especially if you're breastfeeding or bottle-feeding.

What Is Colic?

Infant colic is commonly defined as crying for more than 3 hours a day, more than 3 days a week, for over 3 weeks. It typically peaks between 3 to 6 weeks of age and often improves by 3–4 months.

While the exact cause isn't always known, colic is believed to stem from a combination of:

  • An immature digestive system

  • Gas buildup or air swallowing

  • Heightened sensitivity to stimulation

  • Feeding issues (e.g., fast milk flow, poor latch)

  • Tension or oral dysfunction that affects feeding comfort

Signs of Colic or Gassiness

  • Intense crying episodes, often in the late afternoon or evening

  • Fussiness even after feeding, burping, or diaper changes

  • Pulling knees to chest, arching back, or clenching fists

  • Gassy sounds or frequent burps/farts

How to Help a Gassy or Colicky Baby

1. Optimize Feeding Techniques

Whether breastfeeding or bottle-feeding, feeding posture and technique play a big role in gas and colic symptoms.

  • Get a deep latch: For breastfeeding, make sure baby is chest-to-chest and opens wide before latching.

  • Pace bottle feeds: Hold the bottle so the nipple is either full of milk or fully empty (not both), and pause frequently.

  • Try side-lying feeding: This position slows the flow and can reduce gulping or overfeeding.

  • Watch for a poor seal: Clicking or slurping sounds may indicate your baby is swallowing air. This could be due to:

    • Shallow latch

    • Nipple flow too fast or too slow

    • Oral dysfunction or restrictions (e.g., tongue tie, lip tie)

Pro Tip: If your baby struggles to maintain a seal or seems uncomfortable during feeds, connect with an IBCLC lactation consultant or infant feeding specialist for a full feeding assessment.

2. Burping & After-Feeding Care

  • Burp during and after feeds with gentle pressure on baby’s tummy or upright over your shoulder.

  • Keep your baby upright for 10–15 minutes after feeding to help prevent spit-up and gas buildup.

3. Soothing Techniques That Work

When babies are crying, they may swallow even more air. These techniques can reduce crying and help relieve gas:

The 5 S’s (Dr. Harvey Karp):

  1. Swaddle – Use a swaddle that allows mobility, like Love to Dream Swaddle (size small, medium, transition size when babies start rolling), which helps babies squirm and self-soothe while staying safe.

  2. Side/Stomach Holding – For soothing (not sleep).

  3. Shushing – Use white noise or calming sounds.

  4. Swinging – Gentle rhythmic motion helps calm the nervous system.

  5. Sucking – Try a pacifier like the Philips Avent Soothie (0-3 months, 3-18 months) to relax the body and support gas release.

Comfort Positions:

  • Tummy-down on your chest or legs with gentle back rubs

  • Skin-to-skin contact for warmth and bonding

  • Tummy time throughout the day strengthens core muscles and supports digestion

  • Babywearing offers upright support and gentle motion that can reduce crying and pressure in the belly

4. Gas Relief Techniques at Home

  • Tummy massage: Use gentle, clockwise circles on baby’s belly

  • Bicycle legs: Pedal baby’s legs toward the tummy to help release trapped gas

  • Warm baths: Relax tight abdominal muscles and help calm your baby

  • Infant bodywork: Craniosacral therapy or pediatric osteopathic care can address body tension that impacts digestion and feeding

5. Infant Probiotics (With Pediatrician Approval)

Probiotics may help regulate gut flora and ease colic. Some babies see noticeable improvement within 1–2 weeks of daily use.

Trusted options include:

Always check with your pediatrician before introducing probiotics or supplements.

6. When to Talk to a Healthcare Provider

  • Symptoms persist beyond 4 months

  • Poor weight gain or feeding challenges

  • Excessive vomiting or abnormal stools

  • You’re considering Mylicon, glycerite, or fennel-based remedies

  • You want guidance on eliminating foods (like dairy or soy) from your diet while breastfeeding
