Some parents who prefer convertible car seats, which face backwards until your peanut is big enough, are fans of the Britax Roundabout. "I had an infant carrier ... until about 15 months," says Heather G of California, mother to a 19 month old daughter. "Then I bought a convertible hoping to keep her rear-facing for longer. But, her legs got all squished up, so now she is forward-facing."
Toddlers and Preschoolers: Convertible seats and forward-facing seats with five-point harness Convertible car seats and forward-facing seats typically fit children up to 40 lbs, but some higher priced models work until your little munchkin is 60-100 lbs like the Britax Boulevard.
However, some forward-facing seats with the five-point harness can also eventually convert to use with the shoulder belt, such as the Sunshine Kids Radian65, so you won't have to buy a booster.
School-aged children: Booster seats until about 4'9" tall and about 8-12 years of age
Once your sprout outgrows the forward-facing car seat, they'll make their way into a booster seat, such as the Cosco High Rise Booster. For those little passengers who are big enough for the adult seat belt to fit them correctly, look for boosters that offer a weight minimum as low as 33 lbs. like the Combi Dakota Booster. You'll know that your youngster is ready to jump from the car seat to the booster when:
His shoulders are above the top harness slot
His ears reach the top of the seat back
