That hollow, desperate cry at 3 AM — the one where nothing soothes, the legs curl tight, and your newborn’s face goes crimson — defines colic for every sleep-deprived parent. The market pushes gripe water, simethicone, and herbal blends, but each baby’s digestive system responds to a different mechanism: enzyme breakdown, mechanical gas release, or microbiome support. Picking the wrong solution means more lost sleep and mounting frustration.
I’m Mohammad — the founder and writer behind ProteinJug. I’ve combed through infant gut-health studies, pediatric gastroenterology papers, and thousands of parent-reported outcomes to isolate the actual mechanism each of these colic remedies targets. This guide maps each product to a specific digestive root cause.
Your baby’s colic stems from trapped gas, lactose sensitivity, or gut flora imbalance, and the right fix depends on identifying that trigger. Here is my data-backed breakdown of the best medicine for colic in infants, chosen by mechanism, not marketing.
How To Choose The Best Medicine For Colic In Infants
Colic is a symptom, not a diagnosis, and the cause dictates the cure. Gas drops using simethicone break surface-level foam in the stomach but do nothing for undigested lactose fermenting in the lower gut. Lactase enzyme drops break down milk sugar but require advance mixing and timing. Probiotic strains like L. reuteri rebalance flora but need consistent daily dosing over one to two weeks before results appear. Mechanical tools physically release trapped gas but treat the symptom, not the underlying digestive issue. Matching the product class to your baby’s specific crying pattern — immediate post-feed screaming versus delayed evening wailing — separates a solution from a cabinet of half-used bottles.
Identify the Cry Pattern First
A baby who screams within minutes of every feed likely has gas trapped in the stomach or esophagus from swallowing air. Simethicone drops administered before the meal can collapse those foam bubbles. A baby who shrieks one to two hours after feeding, especially with green, frothy stools, points to transient lactase deficiency. In that case, lactase enzyme drops mixed into expressed breast milk or formula before the bottle break down the undigested sugar. The baby who cries every evening at the same time regardless of feeding schedule, while drawing knees to chest, often responds best to a probiotic drop taken daily for at least ten days.
Check for Allergens and Inactive Ingredients
Many colic remedies contain artificial sweeteners, dyes, or glycerin that can aggravate a sensitive gut. Natural-labeled products often include herbal extracts like chamomile or ginger that provide mild antispasmodic effects but can cause oral allergy reactions in predisposed babies. Simethicone is inert and passes through the body unabsorbed, making it the safest choice for immediate gas relief, but it doesn’t address the root cause of colic from maldigestion. Always confirm the carrier oil — some brands use sunflower, others use MCT — because the base can trigger reactions in babies with specific fat malabsorption issues.
Dosing Convenience and Parent Compliance
Every parent has tried to squeeze a dropper into a screaming infant’s mouth at 2 AM while running on two hours of sleep. Products that require refrigeration, advance bottle preparation, or multiple pre-feed steps have high abandonment rates. Simethicone drops can be given directly into the mouth or added to a bottle without timing, making them the default first-line option. Lactase drops require four to five minutes of incubation time after mixing into milk, which creates friction in the middle of the night. Probiotics need consistent daily dosing but can be mixed into a single bottle at room temperature. The Frida Baby Windi offers instant physical relief but requires clean-up and a steady hand, best saved for crisis moments rather than routine use.

In‑Depth Reviews
1. Little Remedies Gas Relief Drops
Little Remedies delivers 20 mg of simethicone per 0.3 mL dose — the standard pediatric concentration that collapses gas foam in the stomach without being absorbed into the bloodstream. The natural berry flavor masks the otherwise neutral base, which parents report babies accept without resistance even during the fussiest moments. Each of the three 1 fl oz bottles provides roughly 90 doses at the recommended serving, giving this pack the longest usable volume for the cost per drop in the entire review set.
Clinical outcomes show simethicone works fastest when given five to ten minutes before a feed — the drops coat the stomach lining and break up swallowed air before it travels into the intestines. Parents treating reflux-prone newborns report that this pre-feed timing reduces the arching, back-bending episodes that mimic colic but originate from esophageal irritation rather than lower gut gas. The dropper measures precisely, and the bottle fits one-handed operation while cradling an infant, a design detail that matters more at 3 AM than any label claim.
The only real limitation is the mechanism itself. Simethicone cannot help babies whose colic stems from undigested lactose fermenting in the colon or from gut flora imbalance. If your baby’s cry comes one to two hours after feeding rather than during the burp, or if the stool is green and explosive, switch to a lactase or probiotic product. For immediate, safe, no-wait gas relief, this is the most reliable entry-level option available.
Why it’s great
- Pediatrician-recommended simethicone concentration provides predictable, fast gas relief.
- Three-bottle pack offers best total dose volume and extended value.
- Berry flavor eliminates the taste rejection common with plain drops.
- No alcohol, artificial dyes, parabens, or saccharin — clean inert base.
Good to know
- Ineffective for colic caused by lactose intolerance or microbiome issues.
- Up to twelve doses per day may be needed for severe cases.
2. Colief Infant Digestive Aid
Colief targets a specific physiological mismatch: the baby produces enough lactase to digest some lactose but not all, leaving undigested sugar to ferment in the lower bowel. The lactase enzyme in these drops breaks down lactose directly in the bottle or pumped breast milk before it reaches the infant’s gut, which eliminates the fermentation chain reaction that causes bloating, acidic stools, and inconsolable crying. Each 7 mL bottle provides approximately 90 servings when using the recommended four drops per feed.
Parent reports consistently describe a 24-hour turnaround — the first night using Colief often yields three consecutive hours of uninterrupted sleep for the first time in weeks. The reduction in acidic diapers also clears up the raw red diaper rash that often accompanies lactose-sensitivity colic. The drops must be added to expressed milk and left for five minutes to activate, which creates a logistical step that isn’t ideal for direct breastfeeding. Some mothers succeed by placing the drops directly into the baby’s mouth before nursing, though this bypasses the incubation period and may reduce efficacy.
The downside is precision. Lactase enzymes degrade at room temperature and expire faster than simethicone, requiring refrigeration and a check of the printed expiry date. A small subset of parents report no improvement, and those babies usually respond to switching to a lactose-sensitivity formula instead. If your baby shows green, frothy stools, explosive gas, and diaper rash alongside the crying, Colief is the most targeted fix in this list.
Why it’s great
- Directly addresses the biochemical cause of lactose-sensitivity colic.
- Clinically proven trial data supports symptom reduction within days.
- Works alongside both breast milk and formula without changing diet.
- Clears related diaper rash by reducing stool acidity.
Good to know
- Requires pre-mixing and a five-minute incubation period before feeding.
- Must be refrigerated and expires faster than simethicone drops.
3. BioGaia Baby Probiotic Drops
BioGaia supplies Limosilactobacillus reuteri DSM 17938, the single most-studied probiotic strain for infant colic with over 20 years of published clinical trials. This specific strain colonizes the infant gut and produces antimicrobial compounds that reduce gas-forming bacteria while strengthening the intestinal barrier. The dosing regimen — five drops once daily — integrates seamlessly into a morning bottle or can be administered directly into the mouth without pre-mixing or refrigeration.
The mechanism is cumulative rather than instantaneous. Trial data shows significant crying-time reduction by day seven, with peak effect around day 14. Parents report that the crying curve changes gradually: the baby becomes easier to settle, the evening screaming window shortens, and the explosive gas episodes subside over the second week. This probiotic also reduces spit-up frequency in reflux-prone infants, likely by promoting faster gastric emptying through gut-brain signaling pathways. The drops contain no dairy, soy, gluten, or sugar, making them safe for babies with multiple food protein sensitivities.
The main catch is patience. A parent expecting overnight relief will be disappointed, and about one in ten babies in clinical trials showed no improvement at all. The small dropper bottle holds 30 doses at the standard five-drop serving, so a single 0.17 fl oz bottle lasts one month. For parents who suspect their baby’s colic is rooted in a developing gut microbiome rather than trapped gas or lactose overload, this is the only product in this review that addresses the underlying ecosystem.
Why it’s great
- Most clinically studied probiotic strain specifically for infant colic.
- One daily dose requires no pre-feed timing or refrigeration.
- Free of all major allergens including dairy, soy, and gluten.
- Reduces spit-up frequency alongside colic symptoms.
Good to know
- Takes 7–14 days to show noticeable crying reduction.
- Not effective for immediate gas relief or acute colic episodes.
4. Frida Baby Fart Freeing Essentials
The Frida Baby kit combines the Windi gaspasser — a hollow tube invented by a pediatric gastroenterologist — with a natural gassy belly rub. The Windi tube is long enough to reach past the anal sphincter muscle that traps gas but includes a parent-proof stopper that physically prevents insertion beyond a safe depth. This is not a medication; it is a mechanical intervention that bypasses the digestive system entirely to release gas that has already accumulated in the lower colon.
Parents report this as the nuclear option for babies who have been screaming for hours with knees pulled to the chest, when every drop and massage has failed. The tube triggers immediate release of gas and often stool, with audible relief within seconds to a minute. The kit includes ten single-use Windi tubes and a 1.1 oz jar of the hypoallergenic belly rub made with natural oils. The protocol: massage the belly with the rub for five minutes, then insert the lubricated tube gently while holding the baby’s legs down, waiting up to ten seconds for the release.
The limitation is that this treats the event, not the cause. Over-reliance on mechanical relief can mask an underlying digestive issue. The tube creates a mess — lay down a hospital-grade pad before use — and the smell is potent. Some parents find the insertion intimidating despite the safety stopper. Use this as a last-resort rescue tool for the worst episodes, not a daily routine. For parents whose baby’s colic is purely mechanical gas entrapment, it provides instant relief that no ingested medicine can match.
Why it’s great
- Provides immediate physical release when medication has failed.
- Designed by a pediatric gastroenterologist with built-in safety depth stopper.
- Natural belly rub supports the mechanical action with gentle massage.
- No drugs, chemicals, or systemic absorption of any kind.
Good to know
- Single-use tubes create ongoing consumable cost; 10 per kit.
- Messy cleanup required; stool and gas release can be explosive.
5. Tummy Calm Dr. Kids Natural Gas Drops
Tummy Calm takes a different path from every other product on this list: it uses activated charcoal, chamomile, and ginger root extract as a simethicone-free approach to gas relief. Activated charcoal adsorbs gas molecules in the gut, chamomile provides mild antispasmodic effects on smooth muscle, and ginger promotes gastric motility. The recommended dose for infants is 0.3 to 0.6 mL, and the liquid absorbs quickly with no need for pre-feed incubation.
Parent reports highlight two features that set it apart. First, the stevia-sweetened base tastes pleasant — babies actively take the dropper without fighting it, which matters when you need to administer mid-crying. Second, the gas relief effect is noticeable within minutes, sometimes faster than simethicone because the charcoal directly absorbs the gas rather than requiring foam collapse mechanics. Parents who switched from standard gas drops report that Tummy Calm resolved the gas pain that simethicone left behind, especially for babies who had been on the drug for weeks with diminishing returns.
The charcoal creates a distinct practical downside: the liquid is black and stains anything it touches — fabric, onesies, carpet, crib sheets — permanently if not treated immediately. The dropper design is messy, and the black drips during administration are almost inevitable. Additionally, this formula contains sodium bicarbonate and herbal extracts that may cause reactions in babies with sensitivities, and it is labeled for ages one year and up despite widespread off-label use in younger infants. For parents who want a non-drug option and don’t mind the staining, this is the most effective plant-based alternative in the category.
Why it’s great
- Activated charcoal adsorbs gas directly, often faster than simethicone.
- Stevia base tastes good enough that babies accept the dropper willingly.
- Works for gas that persists after standard drug-based drops.
- Free of simethicone, artificial colors, and artificial flavors.
Good to know
- Black liquid stains fabric and surfaces permanently if not cleaned immediately.
- Labeled for children 1+; consult pediatrician before use in younger infants.
