Don’t be in a rush. Use your current car seat until your child reaches the maximum weight or height limit listed on the label. Don’t be in a hurry, because every step forward reduces safety just a bit. Why? If you are in a front-end crash (the most common type of crash) a rear-facing car seat allows your child’s head, neck and spine to move evenly into the seat, not away from it. Each seat is designed for maximum safety at a specific weight, height and age.
Rear-facing car seats. Ride rear-facing until your child is 2 or more years and has outgrown the harness by height or weight. As your child grows you might have to switch from using a smaller rear-facing-only car seat to using a bigger rear-facing convertible car seat that can hold a larger child.
Forward-facing car seats. After your child reaches the weight or height limit for rear-facing, you will then turn the convertible seat forward-facing or use a forward-facing only car seat with a 5-point harness and top tether. Your child may need a forward-facing car seat with a harness that has a higher weight or height limit before moving to a booster seat.
Booster seats. After your child gets too big for the weight or height limits of the forward-facing car seat, use a belt-positioning booster seat with the vehicle lap and shoulder seat belt.
