谢谢提醒,还有高汞的鱼也不能多吃。 from wikipedia Women who are breastfeeding need to be careful about what they eat and drink , since things can be passed to the baby through the breast milk. Just like during pregnancy, breastfeeding women should avoid fish that are high in mercury, and limit lower mercury fish intake. If a woman has alcohol, a small amount can be passed to the baby through breast milk. She should wait to breastfeed at least 2 hours after a single alcoholic drink to avoid passing any alcohol to the baby. Caffeine intake should be kept to no more than 300 milligrams (about one to three cups of regular coffee) per day for breastfeeding women because it may cause problems such as restlessness and irritability in some babies. A diet coke has 46 mg per 12 oz can, and a can of pepsi has 40 mg. Most drinks post their caffeine content on the can or bottle near the nutrition label and ingredients. Some infants are sensitive enough to caffeine to have problems even with smaller amounts of caffeine.
