If your baby does not have enough breast milk and does not eat formula, it is best to eat more foods that promote milk production, such as lean meat and eggs. At the same time drink more soups, you can drink carp and tofu soup, you can also drink soybean and pig’s feet soup, these can promote the increase of milk. If diet doesn’t work, we recommend going to the hospital to have a massage by a masseuse and taking vitamins, and we also recommend acupuncture to promote the flow of milk. Pay attention to let your child suckle more often, which can also promote the increase of milk. Pay attention to getting enough sleep during breastfeeding, don’t be anxious and angry, and exercise properly, which can improve. Add supplementary food to the child at four months to avoid long-term breast milk is not enough to affect the baby’s development.
