The general guideline for caffeine intake while breastfeeding is to limit consumption to about 200 to 300 milligrams per day. This amount is considered safe by sources like the American College of Obstetricians and Gynecologists (up to 200 mg) and the CDC and La Leche League International (up to 300 mg), equating to about two to three cups of coffee daily. Moderate caffeine intake usually does not cause adverse effects in breastfed babies, though some infants, especially preemies and newborns, may be more sensitive and show fussiness or sleep disturbances if the mother consumes more caffeine. It is recommended to time caffeine intake with feedings to minimize caffeine exposure to the baby and watch for any signs of sensitivity. Excessive caffeine intake (more than about 10 cups of coffee daily) may cause fussiness and sleep problems in infants and may affect the mother as well. There is no need to "pump and dump" breast milk after caffeine consumption in moderate amounts.
