If Breastfeeding:

Things to Try:

  • β€’Hold upright after feeding

Switching Formulas:

  • β€’Try "sensitive" or "gentle" formulas
  • β€’Hypoallergenic formulas if suspected allergy
  • β€’Give new formula 2 weeks to see if helps
  • β€’Switching frequently doesn't help

Both Breast and Formula:

  • β€’Keep upright after feeding
  • β€’Smaller, more frequent feedings may help
