Baby Gas and Colic Remedies: What Actually Works
Gas and colic cause some of the most distressing hours of early parenthood. The baby is in obvious discomfort, crying is prolonged, and parents feel helpless. Understanding what's actually happening, and what remedies have genuine evidence, helps navigate this difficult period.
Gas vs Colic: What's the Difference?
Gas is trapped air in the gastrointestinal tract that causes distension and discomfort. It has a clear physical cause, air swallowed during feeding, or gas produced by gut bacteria, and responds to physical interventions like winding and tummy massage.
Colic is clinically defined as crying for more than 3 hours per day, more than 3 days per week, for more than 3 weeks (Wessel criteria) in an otherwise healthy baby. Its cause is not fully understood. Gas is often associated with colic but not its definitive cause, many colicky babies don't have excessive gas, and many gassy babies are not colicky.
The key fact about colic: it resolves on its own by 3–4 months in the vast majority of cases, regardless of treatment. This doesn't make the weeks before that easier, but it does mean that most "remedies" that parents report working may be coinciding with the natural resolution rather than causing it.
Winding Techniques That Work
- Over the shoulder: Baby's chin rests on your shoulder, tummy pressed against your chest. Pat firmly on the mid-back. Most effective position for most babies.
- Sitting upright: Support baby in a sitting position on your lap, leaning slightly forward. One hand supports the chest and chin; the other pats the back. Good for babies who resist the shoulder position.
- Face down on your lap: Baby lies across your lap, head slightly lower than their bottom, facing down. Gentle back rubbing or patting. Effective but harder to do one-handed.
- Wind halfway through a feed. not just at the end. For bottle-fed babies particularly, a mid-feed wind reduces the total air swallowed before discomfort builds.
Remedies Reviewed by Evidence
| Remedy | Evidence | Notes |
|---|---|---|
| Lactobacillus reuteri (probiotic drops) | Good, multiple RCTs | Reduces colic crying time by ~50% in breastfed babies. Less evidence in formula-fed. Biogaia Protectis is the most studied brand. |
| Simethicone (Infacol, Dentinox) | Mixed, reduces gas but not colic | Breaks down gas bubbles effectively. Reduces gas discomfort but meta-analyses show no significant effect on colic crying. Safe and worth trying for gas specifically. |
| Bicycle legs / tummy massage | Moderate, physiological rationale | Moving legs in cycling motion and firm circular tummy massage helps move trapped gas along the bowel. Anecdotally very effective; limited RCT data but logical mechanism. |
| Gripe water | Limited. no quality RCTs | Widely used across Europe. No quality clinical trial evidence of efficacy. Ingredients vary by brand. Not harmful; may provide benefit through warm fluid or parent-baby interaction. |
| Anti-colic bottles | Good for gas, see our guide | Reduces air swallowing during feeding. Effective for gas; less evidence for colic. |
| Warm compress (warm towel on tummy) | Limited | Warmth relaxes abdominal muscles. Physiologically plausible; limited formal evidence. Safe and worth trying. |
Maternal Diet and Breastfed Babies
The relationship between maternal diet and infant colic/gas is more complicated than often presented. A systematic review found that cow's milk protein elimination in breastfeeding mothers reduced colic symptoms in some babies, but the effect was not universal and the research quality was moderate.
Before making significant dietary changes while breastfeeding:
- Keep a 2-week food diary alongside baby's symptom pattern before eliminating anything
- Eliminate one food at a time (not multiple simultaneously) to identify the cause clearly
- Allow 2 weeks after elimination before concluding whether it helps
- Consult a dietitian before eliminating dairy, breastfeeding mothers need adequate calcium
