1. Pay attention to the mother's nutrition during pregnancy, keep proper physical activity, and ensure the normal weight of the baby at birth. The normal birth weight of a baby is 2.5 kg to 4 kg.
2. After the child is born, we should insist on breastfeeding as much as possible. Breast milk is not only the best food for children, but also the key measure to prevent infants from obesity.
3. Avoid overfeeding and don't let children eat too many snacks and high-calorie foods.
4. Encourage children to exercise more and ensure at least 1 hour of outdoor activities every day.
