Lactose intolerant babies can be breastfed, but it is fine to take lactase before giving breast milk each time. Lactose intolerance is due to the baby’s inability to digest the lactose present in the milk, and eating breast milk may cause bloating and diarrhea, and these symptoms will be reduced with the addition of lactase, and after a few weeks or 1-2 months, the child’s condition will improve and the number of doses of lactase can be gradually reduced and finally stopped. If your baby is artificially fed and has lactase intolerance, you can use goat milk powder or lactose-free milk powder for feeding. Because the lactose content in goat milk powder is relatively low, as the baby grows, when the baby can add some supplementary food, the nutritional supplement can be diversified a little. It is recommended that parents give their babies a full examination to check whether lactose intolerance is caused by other diseases and pay more attention to changes in the baby.
