How This Protocol Works
Simple Explanation
Infant colic is defined as episodes of crying for more than 3 hours a day, more than 3 days a week, for more than 3 weeks in an otherwise healthy infant. It typically starts around 2-3 weeks of age and usually resolves by 3-4 months. Colic affects about 10-25% of infants.
IMPORTANT: Colic is NOT harmful to the baby long-term, but it is extremely stressful for parents.
WHEN TO SEE A DOCTOR:
POSSIBLE CONTRIBUTING FACTORS:
NON-SUPPLEMENT STRATEGIES:
* Lactobacillus reuteri DSM 17938 is the most studied probiotic for colic. Multiple RCTs show it reduces crying time, especially in breastfed infants.
* Fennel has traditional use for infant digestive discomfort and some clinical evidence.
* Simethicone is commonly used for gas but evidence is mixed.
Expected timeline: Probiotics may show benefit within 1-2 weeks. Colic typically resolves by 3-4 months regardless of treatment.
Clinical Perspective
Infantile Colic: Defined by Wessel criteria (rule of 3s) or Rome IV criteria: recurrent episodes of crying, fussing, or irritability in infants <5 months without obvious cause; no failure to thrive. Prevalence: 10-25%. Peak: 6 weeks. Resolution: 90% by 4 months. Etiology unclear: proposed factors include gut dysmotility, gut microbiome immaturity, cow's milk protein allergy, lactose malabsorption, feeding techniques, parental anxiety.
CRITICAL: Rule out red flags - vomiting (pyloric stenosis, obstruction), bloody stool (intussusception, CMPA), fever (infection), poor weight gain (feeding problems, metabolic). Colic is diagnosis of exclusion. Most important: reassure parents, colic is self-limited and does not harm infant. Address parental stress, screen for postpartum depression. SIDS risk from unsafe sleep practices due to exhaustion.
* Lactobacillus reuteri DSM 17938 (A-grade): Best evidence. Meta-analysis: (PMID: 29356478). Cochrane: (PMID: 25007694). 10^8 CFU daily. Reduces crying ~50 min/day. Most effective in breastfed infants.
* Simethicone (C-grade): Gas reduction. Systematic review: (PMID: 24062479). No better than placebo in trials but commonly used. Safe.
* Fennel Extract (B-grade): Antispasmodic. RCT: (PMID: 12868253). Traditional use. Caution: estragole content, use appropriate products.
* Chamomile (C-grade): Traditional. RCT: (PMID: 8039122). Often in combination products.
* Lactase Drops (C-grade): For possible lactose intolerance. Trial: (PMID: 8536550). May help subset of infants.
* Vitamin D (C-grade): Emerging evidence. Observational: (PMID: 28750270). 400 IU for infant or maternal supplementation if breastfeeding.
Assessment targets: Crying diary (duration, frequency), feeding patterns, weight gain, stool patterns, parental stress assessment.
Protocol notes: CMPA (cow's milk protein allergy): consider if severe, bloody stool, eczema, family history - trial elimination diet (mother if breastfeeding) or extensively hydrolyzed/amino acid formula. Probiotics: L. reuteri has best evidence; other strains less studied. Formula: partially hydrolyzed formulas not proven; extensively hydrolyzed for CMPA. Gripe water: many commercial products; variable ingredients; some contain alcohol or sugar - check labels. Chiropractic/osteopathy: some parents report benefit; limited evidence. Maternal diet: eliminate dairy 2-3 weeks if breastfeeding; caffeine reduction. Feeding technique: adequate burping, appropriate bottle nipple flow, upright positioning. Environment: reduce overstimulation, consistent routines, calm caregiving. Parent support: emphasize colic is NOT their fault; respite care; safe infant space when overwhelmed; screen for postpartum depression/anxiety. Safety: never shake baby; safe sleep practices even when exhausted.
