Does anyone have a recommendation on a travel friendly booster car seat? My 5 yr old is using a Britax Frontier and I'm not interested in lugging it on a plane cross country in an upcoming trip. I thought something like the Bubble Bum looked lightweight and portable for one-week use in a rental car. Would love to know if anyone has this or similar item...
