How to limit kids' tech use is important for their overall well-being. Experts recommend that children under the age of 2 should have no screen time, while kids between 2 and 5 years old should have no more than an hour of screen time per day. For children over 5 years old, parents should set reasonable limits on their tech use, such as no screens during meals or before bedtime. Encouraging physical activity, outdoor play, and face-to-face social interactions are also important for children's development.
