Grasp the sliver firmly with tweezers and pull it out at the same angle it went in. Call your child's physician if you can't remove a sliver. Observe your child for the first 2 hours after the injury. Encourage your child to lie down and rest until he no longer has symptoms. Have your child sleep near you so you can periodically check on him.
Vomiting is common after head injuries.
Don't give your child acetaminophen, aspirin, or ibuprofen because your physician needs to know your child's reaction to the injury. If your child's head hurts badly enough to need a pain reliever, your physician should check him. Although your child is probably fine, watching him for 48 hours will ensure that you don't miss any serious complication. After 48 hours, however, your child should return to a normal routine and full activity. Arouse him until he is walking and talking normally.
