 Mom, is this how you feed a hamster? Uh, I think so. Is my homework right? Hmm, I think so. Is this milk still good? Uh, I think so. When it comes to parenting, sometimes it's okay to think you know. But when it's something as important as your child's car seat, don't just think. Know. Double check if your child is in the right seat for their age and size. It'll help protect them in a car crash. Don't just think. Know by visiting NHTSA.gov slash the right seat. A message from NHTSA and the Ad Council.
