Colic Home Remedies for Babies: What Actually Works
Evidence-based strategies to soothe a colicky baby, from Harvey Karp's 5 S's to probiotics — plus the red flags that mean it's not colic.
What Is Colic, Exactly?
Colic is defined by Wessel's Rule of 3s: inconsolable crying for more than 3 hours a day, more than 3 days a week, for at least 3 weeks in an otherwise healthy, well-fed baby. It affects roughly 1 in 5 infants and is one of the top reasons parents call their pediatrician in the first few months.
Colic typically begins around 2 to 3 weeks of age, peaks at about 6 weeks, and usually resolves on its own by 3 to 4 months. Despite decades of research, there is no single confirmed cause. Leading theories include an immature digestive system still learning to process food, overstimulation from the baby adjusting to life outside the womb, and in some cases, a sensitivity to proteins in breast milk or formula (most commonly cow's milk protein).
- Affects approximately 20% of all newborns regardless of feeding method, birth order, or gender
- Episodes often cluster in the late afternoon and evening hours
- Baby may clench fists, arch the back, pull legs toward the abdomen, and turn red while crying
- Between episodes, the baby is typically content, eating well, and gaining weight normally
The 5 S's: The Gold Standard for Soothing Colic
Pediatrician Dr. Harvey Karp developed the 5 S's technique based on the idea that newborns benefit from recreating the womb environment. This approach has been widely adopted by hospitals and pediatricians as the first-line soothing strategy for colicky babies.
- Swaddling: Wrap your baby snugly in a blanket with arms at the sides. This prevents the startle reflex from waking them and provides a sense of security similar to the womb. Stop swaddling once baby shows signs of rolling (typically around 2 months).
- Side/Stomach holding: Hold baby on their side or stomach across your forearm or lap while they're awake. This position puts gentle pressure on the belly that can ease gas pain. Always place baby on their back for sleep.
- Shushing: Make a loud "shhhh" sound near baby's ear, matching or slightly exceeding the volume of their crying. The sound mimics blood flow they heard in the womb. A white noise machine set at 65 dB works as a hands-free alternative.
- Swinging: Small, quick, rhythmic movements (not shaking) support the head and neck while gently jiggling. Think of the constant motion baby felt during pregnancy. A swing or vibrating bouncer can help when your arms need a break.
- Sucking: Offer a pacifier, clean finger, or the breast. Non-nutritive sucking activates a calming reflex and lowers the heart rate. If breastfeeding, offering the breast for comfort nursing is perfectly fine.
Additional Remedies That Have Evidence Behind Them
Beyond the 5 S's, several other approaches have shown benefit in clinical studies or are commonly recommended by pediatricians.
- Simethicone gas drops (Mylicon, Little Remedies): These break up gas bubbles in the stomach. While studies show mixed results for colic specifically, they are safe and may help if your baby seems gassy. Give before or after feeds as directed on the package.
- Probiotics — specifically L. reuteri DSM 17938: Multiple randomized controlled trials have shown that this specific probiotic strain reduces crying time in breastfed colicky infants by an average of 50 minutes per day. Available as BioGaia drops. Evidence is stronger for breastfed babies than formula-fed.
- Elimination diet for breastfeeding mothers: If you suspect a food sensitivity, try removing dairy (the most common culprit) from your diet for 2 to 3 weeks. If symptoms improve, you've found the trigger. Other potential triggers include soy, eggs, wheat, and nuts, but eliminate one at a time.
- Warm bath: A warm bath can relax abdominal muscles and help release trapped gas. Some parents find bath time to be the most reliable part of their soothing routine.
- Tummy time on a warm (not hot) towel: Gentle pressure on the abdomen combined with warmth can ease gas discomfort. Always supervise closely and ensure the towel is comfortably warm, not hot.
- Bicycle legs: Lay baby on their back and gently cycle their legs in a bicycling motion. This helps move gas through the intestines and often produces immediate relief through passing gas.
What Doesn't Work (and What to Avoid)
Some popular colic remedies lack evidence or can actually be harmful. Knowing what to skip is just as important as knowing what to try.
- Gripe water: Despite its popularity, there is no scientific evidence that gripe water treats colic. Some brands contain ingredients like alcohol, sugar, or sodium bicarbonate that are not safe for infants.
- Switching formulas repeatedly: Rapidly cycling through formulas doesn't help and can upset a baby's digestion further. If you want to try a different formula, consult your pediatrician and give each one at least 5 to 7 days.
- Herbal teas or supplements: Fennel tea, chamomile, and other herbal remedies marketed for colic are not regulated for infant safety and can interfere with nutrition if they fill up the baby's small stomach.
- Restricting feeding: A colicky baby who wants to eat should be fed. Overfeeding concerns are valid, but underfeeding a crying baby will only increase distress.
When It's NOT Colic: Red Flags to Watch For
True colic occurs in a baby who is otherwise thriving. If your baby has any of the following symptoms alongside excessive crying, the cause may be something other than colic and warrants a prompt call to your pediatrician.
- Poor weight gain or weight loss: A colicky baby should still be gaining weight on their growth curve. Falling off the curve suggests a feeding issue, reflux, or food allergy.
- Blood or mucus in the stool: This can indicate a cow's milk protein allergy or intolerance, which requires dietary changes, not just soothing techniques.
- Fever (100.4°F / 38°C or higher): Any fever in a baby under 3 months requires immediate medical evaluation. Colic does not cause fever.
- Persistent vomiting (not just spit-up): Forceful or projectile vomiting may indicate pyloric stenosis or severe reflux, both of which need medical treatment.
- Lethargy or refusal to eat: A baby who is difficult to wake or refuses feeds is showing signs that something beyond colic is going on.
Taking Care of Yourself Through the Colic Phase
Colic is temporary for the baby but can feel endless for parents. Studies show that parents of colicky babies are at higher risk for postpartum depression, relationship strain, and caregiver burnout. Your well-being matters just as much as your baby's.
- Take shifts with your partner, a family member, or a trusted friend so each caregiver gets uninterrupted rest
- Use earplugs or noise-canceling headphones to reduce the stress response to crying while still being present and attentive
- Talk to your OB or midwife if you notice signs of postpartum depression — persistent sadness, anxiety, difficulty bonding, or thoughts of harm
- Remember that colic is not caused by anything you did wrong. It is a developmental phase, not a reflection of your parenting
- Connect with other parents going through colic via support groups (online forums like r/NewParents or local hospital support groups can provide reassurance)
