Where can I find info about the safest booster seats? My 7-year-old is outgrowing his Radian65. He's fine on height and weight, but the strap is really tight in the crotch and he's been complaining of discomfort every time we go anywhere in the car. I'm fairly comfortable moving him to a booster at this age.
Is the Graco High Back Turbobooster a good choice? Or can you recommend something better? Price is an issue, because I have an infant or convertible seat (no idea which one yet), a second seat for my 5-year-old (Nautilus most likely), and two of whatever booster I decide on to purchase in the next few months.
