The Graco Nautilis!! (they come in cute girl prints too)

5 point harness to 65 lbs - 5 point harness is the safest and should be used as long as possible!
converts to a high back belt positon booster- can be used when your child is 4 years and 40 lbs and should stay a high back booster until 7 years old
and then later a no back booster -until they are 8-12 years, 4'9" tall
and can meet these criteria
-
Does the child sit all the way back against the auto seat?
-
Do the child's knees bend comfortably at the edge of the auto sea?.
-
Is the lap belt touching the top of the thighs, not the tummy?
-
Is the shoulder belt centered on the shoulder and chest?
-
Can the child stay seated like this for the whole trip?
