I’m a real stickler when it comes to car seat safety. The one thing you NEVER want to do is buy a used seat or continue using a car seat that has been involved in an accident. Without knowing the car seats true history, you could be putting your child at risk. Looking to upgrade your child’s car seat? If your little one is outgrowing their infant seat or car seat, or perhaps you need an extra car seat, booster seat, etc.
