1. Balanced diet: A 2-year-old baby's diet should include five types of food, namely, grains, vegetables, fruits, meat and beans. You should get enough protein, carbohydrate, fat, vitamins and minerals every day.

2. Avoid too much sugar: Too much sugar can lead to problems such as baby obesity and tooth decay, so you should try to avoid giving your baby sugary drinks and snacks.

3. Pay attention to food safety: the baby's immune system is not fully developed, and it is easy to be infected with bacteria and viruses in food. Therefore, we should pay attention to the hygiene and safety of food and avoid eating expired or stale food.

4. Appropriately increase the intake of cellulose: The intestinal function of the 2-year-old baby is not perfect enough, and it is prone to constipation and other problems. Therefore, the baby's dietary fiber intake should be appropriately increased, such as eating more vegetables and fruits.

5. Pay attention to eating habits: 2-year-old babies can eat by themselves. Parents should pay attention to cultivate their baby's good eating habits, such as regular and quantitative, chewing slowly and not picky eaters.
