Three-Month Colic in Babies

Three-month colic — also called a regulatory disorder — follows a typical pattern: it starts around week 2, peaks around week 6, and usually disappears as if by magic at 3-4 months. These weeks are often the hardest time for parents. You are not alone in this.

Posibles Causas

  • 1Immature nervous system — baby cannot yet filter stimuli (sensory overload in the evening)
  • 2Immature digestive tract: gut bacteria colonisation still developing
  • 3Increased air swallowing during feeding (aerophagia)
  • 4Possible food intolerance via breast milk (cow's milk protein, caffeine)
  • 5Tobacco smoke exposure demonstrably increases risk

Qué Puedes Hacer

  • Swaddling: firm wrapping provides security and reduces the Moro reflex
  • White noise (hairdryer, vacuum, app) — mimics sounds from the womb
  • Colic hold: place baby tummy-down on your forearm, gently rock
  • Probiotics (Lactobacillus reuteri) — studies show improvement in breastfed babies
  • Baby carrier or sling — body contact and movement are soothing

¿Cuándo Consultar al Médico?

  • Crying exceeds the rule of 3 (more than 3 hours, more than 3 days/week, more than 3 weeks)
  • Baby is not gaining weight or is losing weight
  • Vomiting (not spitting up!) after every feed
  • Blood in stool — investigate cow's milk protein allergy
  • Parent feels at breaking point → shaken baby prevention: put baby down safely and get help

Notas Según la Edad

Week 1-2: Colic begins. Week 6: Peak — crying is most intense. Week 8-10: Slow improvement starts. Month 3-4: It stops for 90% of babies. If it continues beyond month 4, other causes (reflux, CMPA) should be investigated. IMPORTANT: The crying is NOT your fault. You are a good parent.

Preguntas Frecuentes

Is the rule of 3 really accurate?
The Wessel criteria (rule of 3) are the classic definition: a baby has colic if they cry for more than 3 hours a day, on more than 3 days per week, for more than 3 weeks. Many experts now find the rule too rigid — if YOU feel something isn't right, that's reason enough for a doctor's visit.
Should I change my diet while breastfeeding?
Try eliminating dairy products for 2 weeks — in about 5-10% of colicky babies, CMPA is the cause. Caffeine, gas-producing foods, and heavily spiced foods may also play a role. Keep a food diary.
What should I do when I can't cope anymore?
This is the most important advice: when you're at your limit, put your baby safely on their back in the cot and leave the room. Breathe. Call someone — partner, parents, friends, midwife, crying clinic. Putting a crying baby down safely is ALWAYS better than shaking. NEVER shake a baby.
Do anti-gas drops like simethicone help?
Simethicone dissolves gas bubbles in the gut and may help with bloating. However, studies show no reliable effect on colic. It's worth trying — it has no side effects. Probiotics (L. reuteri) have better scientific evidence.
