when the baby is 6 months old, it can be properly added with complementary food. During this period, it can be properly added to the baby once a day, and every time it is added at about 7:~8: every morning. The principle of adding complementary food is to balance nutrition, mix meat and vegetables, and add from less to more, from fine to coarse. Egg yolk and rice flour can be properly added to the baby. All kinds of vegetable juices can make some fruit puree for your baby to eat in daily life, which can maintain a balanced nutrition and effectively promote your child's physical growth and development. In the process of adding complementary food, we should also observe the state of children's defecation frequently. If there are symptoms of constipation or diarrhea, this situation can give children probiotics to adjust the imbalance of gastrointestinal flora, which can effectively improve the symptoms of constipation or diarrhea.
