If Junior is one of those kids who spends the days "bouncing off the walls," then you already know you have a hyper child. In many children, however, being hyper is a bit more subtle or comes only after eating an extra giant serving of ice cream. Learning what constitutes "normal excited" versus non-stop movement will help you understand your child better.
Look for constant fidgeting that's not associated with any particular activity. Some over-excitement is normal if you're leaving for Disneyworld or if your child is anxious because there's a doctor's appointment coming up. But if every day feels like you're planning a Disney trip, then you have a problem.
Suggest a quiet activity to your child, such as coloring or watching a movie together. A hyper child will have trouble concentrating because it requires staying in the same position for long periods of time. She'll probably need to ask a million questions during a movie or she'll get up to fetch something several times -- expect lots of "I need a blanket," "I'm thirsty" and "I need a second pillow."
Ask your child's babysitter about his behavior. Hyper children often have a hard time staying in the same place and might be labeled as disobedient because they can't follow directions or don't seem to be able to listen. This is true even if your child is well educated and respectful.
Pay attention when your child plays by herself. Hyper children often have a hard time playing quietly, according to Mayo Clinic. Even when playing alone, they might either talk to themselves, bolt out singing or try talking to you while involved in their own activities. Asking a question often results in non-stop talk, sometimes not even related to what you asked in the first place. That is, if she even gives you the chance to finish your question.
