Prince William and Kate Middleton Have Used Same Car Seat for All 3 Kids

"I think they know that we are one of the safest brands out there. And, not only that, we're a British company," says Kate Clark of Britax. It's not available in the U.S. but Britax does offer a similar one for royalty-worthy Americans. InsideEdition.com's Keleigh Nealon (http://twitter.com/KeleighNealon) has more.
