When deciding on a car seat, you need to consider three factors-babies age, weight, and height. Based on these, you can determine what type of car seat you need. For instance, infant car seats installed rear-faced usually have a weight limit between 0-35 lbs. They are meant for infants only. Forward-facing car seats will be more suitable for toddlers that range between 22-65 pounds. You can also pick convertible car seats that accommodate both infant and toddler age. A booster car seat is your final option, and it’s used with preschoolers as well as kids up to 13 years old.
