1. Nurses should kindly remind children to go to the toilet before and after the activity. It is required to remind children not to talk when defecating, and the defecation time should not exceed 10 minutes. 2. Gradually cultivate the habit of regular defecation for children every day (preferably in the morning). 3. Guide the child to aim at the toilet, and don't wait outside. 4. Teach your child to wipe his ass after defecation. Small class children can let the teacher wipe their bottoms when they first enter the park, and middle and large class children can wipe their bottoms after defecation. When teaching children to wipe their bottoms, wipe them from front to back, and fold the paper thick and wipe it twice. Paper should be cut in advance and put in a box in a fixed position, and children can take it by themselves. 5. Instruct children to pull up pants when defecating. In winter, keep your legs warm. Help the child put on his pants after urinating. Pay attention to keep your abdomen warm. Pay attention to inspection and help individuals.
