For some states, it is required by law that all children under the age of 2 years have to sit in a rear facing option when riding in any automobile. The reasoning behind this is because it is just simply more safe for your child. Many options out there on the market that will grow along with your child have the option to mount the unit in the rear when they are under 2, and then it will be able to turn around and mount to the front when they are over 2 years of age. It’s important that you never put a rear facing option in the front of an automobile because many vehicles now have airbags that deploy on the passenger side.
