First, the newborn baby, due to the amount of breast milk secretion is relatively small, or the mother is the nipple of the invagination, or the nipple is relatively large, resulting in the baby sucking more difficult situation, the child will not appear to breast milk. Therefore, first of all, the mother should take more rest to increase the secretion of milk, and can use nipple protectors to improve the situation of nipple invagination. If the nipple is too large to suck, the breast milk can be sucked out and sucked into the bottle before feeding the child. Secondly, because the mother eats special food with special smell, which causes some changes in the taste of breast milk, some children are more sensitive and may not eat breast milk for a short time, so parents should pay attention to avoid eating stimulating food. Thirdly, in 3-4 months old children, there will be a period of anorexia, which usually lasts for about a week. Parents do not need to be anxious if it is an anorexic period, after this time the child will eat milk normally.
