So I haven't been here in a long time since my older kids are almost 11 and 8. My oldest is 5'2 and has been seat belt only for almost a year, and my 8 yo is in a backless. Then...we had a blessed surprise by having our 3rd baby girl in February (she's 17.5 lbs in a Chicco Keyfit 30). I'm excited to see 50 pound rear-facing seats!! My oldest had a 33 lb Britax, and my middle had a 40 lb Graco MyRide when it first came out. So now I'm wondering, which is better? A Diono 50 pounder or the Graco Extend2Fit? My kids tend to be heavy with longer torsos. I'm kind of liking the looks of the Graco (plus being almost $200 cheaper), but is there any reason I should steer clear of it for the Diono? Thanks!!
