The training methods for 4-year-old children to concentrate on attention include patient guidance, exercising the child’s self-restraint, and eliminating external interference. 1. Patient guidance: If the child is not concentrating, parents should not scold the child, and should not blame too much should patiently guide the child to the right thing, such as eating. 2. Exercise the child’s self-restraint: you should let the child participate in some collective activities, such as kindergarten sports activities, to cultivate the child’s self-restraint and the team’s sense of order, which can help to focus attention. 3. Eliminate external interference: when the child focuses on doing a thing, parents should minimize the surrounding stimuli, such as auditory stimulation or taste stimulation, to create a single environment for the child to help focus. If a 4-year-old child has persistent inattention and it is accompanied by other abnormalities, such as behavioral abnormalities, it is very likely to be ADHD, and should go to the hospital in time.
