Mild to Moderate Head Injuries
After a mild or moderate head injury, most children will not have problems beyond a cut, bruise, or swelling on the scalp. Some children also have headaches that you can treat with acetaminophen (Tylenol).
However, since every child and injury is different, it is a good idea to watch your child for unexpected changes for several days following an injury. While there is nothing wrong with awakening your child periodically through the night for reassurance, it is not necessary unless the doctor instructs you to.
