How to Soothe a Colicky Baby

Immediate Calming Techniques

• Swaddling: Wrap baby snugly in a blanket
• Side/Stomach: Hold baby on their side or stomach

2. Colic Massage

Feeding Adjustments

For Breastfeeding

• Eliminate dairy and caffeine from mom's diet for 2 weeks
• Ensure proper burping after feeding

For Formula Feeding

• Consider hypoallergenic formula

💡 Colic is not the fault of the baby or parents. It's a temporary developmental phase that will pass.

Consult your pediatrician if your baby has:

• Fever above 100.4°F (38°C)
• Significantly reduced feeding
• Vomiting or diarrhea
