Why aggression can show up in preschoolers with ADHD

ADHD aggression in preschoolers is often less about intentional meanness and more about impulsivity, frustration, sensory overload, language limits, and difficulty recovering once upset. A preschooler with ADHD aggressive behavior may hit, bite, throw objects, or lash out quickly when demands change, transitions happen, or another child gets too close. Understanding the pattern behind the behavior is the first step toward choosing strategies that actually fit your child.

Common patterns parents notice

Fast reactions before thinking

Aggression during transitions or demands
