“Getting presents is usually a highlight of the holiday season. But for kids who struggle with self-control, exchanging gifts can often lead to frustration and tantrums.
Opening gifts can be especially hard for kids with ADHD who have impulsivity and trouble managing emotions. They may overreact when they don’t like a gift or were expecting something else. They may get very frustrated having to wait their turn. (Kids who experience sensory overload may have meltdowns.)”
