It is generally not recommended to drink coffee during lactation, because caffeine may enter the milk and have a certain impact on the baby. The half-life of caffeine in healthy people is generally 4~6 hours. If pregnant women drink coffee, it is recommended to breastfeed after 8~ 12 hours to avoid the bad ingredients of coffee from entering the baby's body through milk and affecting the baby.
It doesn't matter if you don't drink much. You can breastfeed immediately after drinking coffee. Although it is possible to secrete some through milk, it generally does not have much impact on children. Because it is only a kind of food, not a medicine, it will not produce the same effect as medicine. But it is best to drink less coffee during breastfeeding. One cup a day, or once in a while, that's all.
If you drink coffee regularly, it may also cause the newborn to fidget and so on. In addition, drinking coffee often may lead to calcium deficiency, which must be paid attention to. Coffee can play a refreshing role, and drinking coffee properly can improve work efficiency.
