Tell children to learn to sit accurately and let them know the benefits of sitting up straight. Some children don't understand the benefits of sitting up straight. Parents can use visual metaphors to let their children really understand the truth of sitting posture. "You see, the policeman's waist is straight, how much he looks like! The baby sits up straight, reads and writes, and is as energetic as a police uncle. He can't be nearsighted and his spine can't bend. As great as a man with indomitable spirit! " With positive example education, children will gradually form their own learning forms with reference learning. 2. Remind the baby to sit down at any time. Parents should investigate and prompt the baby's sitting posture at any time. Remind your baby to sit up straight when reading, and don't lie prone on the table or read with his head tilted. Writing and drawing should adhere to the "three ones", that is, the eyes are one foot away from the table, the chest is punched from the table, and the hand is one inch away from the pen tip. When eating, remind children to reach out their hands, hold a bowl in their left hand, hold a spoon or chopsticks in their right hand, put their feet under the table and stand upright. Promote children to develop accurate dining etiquette, but also promote digestion and eat well. 3. Create a suitable learning environment for the baby. Parents should provide their baby with a chair for students, which is in harmony with his height. Generally speaking, the interval between tables and chairs is suitable for the baby to sit in the chair, and the elbow is just placed on the desktop. Parents should also be careful not to let the baby sit on the soft sofa or bed reading and watching TV, and don't let the baby rely too much on scapegoats when sitting.
