Infant colic refers to episodes of crying for more than 3 hours a day, more than 3 days a week, for over 3 weeks in an otherwise healthy baby. About 20% of babies experience colic between 2 weeks and 4 months of age. This guide covers colic symptoms, causes, and effective soothing techniques.

What is Infant Colic?

Infant colic is excessive crying in a healthy baby without an apparent medical cause. It's diagnosed using the "Rule of Threes" defined by Dr. Morris Wessel in 1954.

Causes of Infant Colic

The exact cause of colic remains unknown, but several factors may contribute.

1. Immature Digestive System

  • Baby's gut is still developing
  • Imbalanced gut microbiome
  • Difficulty digesting lactose

2. Nervous System Development

  • Oversensitivity to stimulation
  • Underdeveloped self-soothing ability
  • Irregular sleep-wake cycle

3. Feeding-Related Factors

  • Swallowing air during feeding
  • Overfeeding or underfeeding
  • Mother's diet affecting breast milk (dairy, caffeine)

4. Environmental Factors

  • Overstimulation (noise, bright lights)
  • Irregular routines
  • Parental stress

How to Soothe a Colicky Baby

Immediate Calming Techniques

1. The 5 S's (Dr. Harvey Karp)

  • Swaddling: Wrap baby snugly in a blanket
  • Side/Stomach: Hold baby on their side or stomach
  • Shushing: Make gentle shushing sounds near baby's ear
  • Swinging: Gently rock or swing baby
  • Sucking: Offer a pacifier or let baby suck on a finger

2. Colic Massage

  • Gentle clockwise belly massage
  • I-L-U massage technique on baby's tummy
  • Bicycle legs: Move baby's legs in a cycling motion
  • Warm hands on belly

3. Environment Adjustments

  • Create a quiet, dim environment
  • Use white noise (vacuum cleaner, rain sounds)
  • Warm bath
  • Car ride or walk outside

Feeding Adjustments

For Breastfeeding

  • Empty one breast completely before switching
  • Eliminate dairy and caffeine from mom's diet for 2 weeks
  • Ensure proper burping after feeding

For Formula Feeding

  • Consider hypoallergenic formula
  • Angle the bottle to minimize air intake
  • Choose appropriate nipple size
  • Burp frequently during feeding
💡 Colic is not the fault of the baby or parents. It's a temporary developmental phase that will pass.

When to See a Doctor

Consult your pediatrician if your baby has:

  • Fever above 100.4°F (38°C)
  • Significantly reduced feeding
  • Vomiting or diarrhea
  • Poor weight gain
  • Blood in stool
  • Symptoms persisting beyond 3-4 months

Tips for Parents

The colic period is challenging for parents too.

  • It's okay to put your baby in a safe place and take a short break
  • Share caregiving duties with your partner or family
  • You don't need to be a perfect parent
  • Seek professional support if needed
