The American Academy of Paediatrics advises against screen time for children under 18 months, except for video chats with family, as it can interfere with critical developmental milestones. For toddlers aged 18 to 24 months, focus on high-quality, interactive programming and watch together to explain content. Limit daily screen time to one hour for preschoolers and prioritize activities that support active play, communication, and learning. When used thoughtfully, digital content can supplement development, but direct interactions with caregivers remain essential for cognitive and social growth.
