It was released yesterday that newer Sunshine Kids Radians can rear face up to 40 pounds!! So exciting. The Radian has almost the tallest shell of any RF seat, so it will even get older children to 40 pounds. Sofi could rear face until she's 6 or 7 with her growth pattern.
Radians (65, 80, and XT) manufactured in or after Septemeber 2008 can now RF up to 40 pounds. Seats manufactured before Sept 2008 can not. There were some structural changes to the seat in September, making the pre and post Sept seats different.
