Kids should generally wait until they are at least 4 years old before eating popcorn. This recommendation is based on choking hazard concerns, as popcorn kernels and pieces can easily get stuck in the airway of young children who haven't developed the molars and chewing skills needed to safely break down popcorn. The American Academy of Pediatrics advises against giving popcorn to children under age 4, and parents should also consider their child's individual chewing ability and maturity, possibly waiting longer if needed. When popcorn is introduced, it should be served in small, manageable pieces with close supervision to reduce choking risks.
