To determine whether it is okay to breastfeed after drinking coffee, it needs to be determined by the amount of coffee drunk and the spleen and stomach function of the child. Firstly, if the amount of coffee drunk by the parents is very small, just a few sips, and the child’s spleen and stomach function is usually good, with no obvious symptoms such as abdominal pain or vomiting, then breastfeeding is possible. Secondly, if the parents drink a lot of coffee and the child’s stomach and intestines are not good, often with abdominal pain, diarrhea, vomiting and other symptoms, it is better not to feed the milk. Otherwise, it will affect the gastrointestinal function of the child, causing the intensification of digestive symptoms in children, such as vomiting obviously, diarrhea, and even fever, etc.
