The main source of energy and nutrients for a one-year-old baby is formula and complementary foods, with complementary foods being the mainstay. At this age children may like the colorfulness of complementary foods as well as the variety of flavors, not drinking formula is not an option, they must drink formula. Most of them drink 250ml each time, up to three times a day, no more than three times, and need to feed more water between feedings. Although small children are capricious and picky, but as long as parents insist, children will naturally give in when they are hungry and will naturally drink milk, such as not wanting to drink milk and only wanting to eat, tell him that there is no food to eat if he does not drink milk, and when he does not see that parents are distressed that he gives in, he will naturally drink milk.
