Three-month-old babies try not to eat bananas, because only from six months can you gradually add some non-dairy foods to your baby, including liquid foods such as fruit and vegetable juices, rice flour, fruit puree, vegetable puree pureed food, and soft rice, rotten noodles, and solid foods such as fruits and vegetables cut into small pieces, which are called complementary foods, or complementary foods for short. The order in which complementary foods are added should begin with the addition of cereals. Next is vegetable juice, vegetable puree and fruit juice, fruit puree, and then animal food, such as egg custard fish, poultry, meat puree and so on. The principle of adding complementary foods is generally a gradual process from less to more, from thin to thick, so three-month-old babies are too young to add.
