If the baby is 10 months old and suddenly does not eat complementary food, parents should firstly have patience, and secondly provide the baby with complementary food with rich colors and forms to increase the baby’s interest. The process of adding complementary foods for 10-month-old babies should be gradual. At the beginning, it is best to choose original complementary foods, such as chopped vegetables, small pieces of fruits, egg yolks, fish and meat. Let babies taste the natural flavors of food and avoid adding salt, sugar and other flavoring agents too early, so that babies will be exposed to foods with strong flavors too early and lose interest in the original flavors of foods without flavoring agents. Parents can encourage babies to grasp food by themselves to increase their interest in eating. You can also try to increase the variety of complementary foods and choose those with bright colors and novel shapes to increase your baby’s interest. At the same time, add foods rich in dietary fiber, such as celery and carrots, to help promote the baby’s digestion. It is very common for 10-month-old babies not to eat complementary foods, parents do not need to worry too much. However, if after the above adjustments, the baby still does not eat complementary foods, we should consult the child health department in a timely manner, and follow the doctor’s advice to intervene.
