My younger daughter is 7 and a half, and finally hit 45 pounds, so we turned her Radian XTSL forward facing. She is 46.5 inches tall. She has known for a long time that she would turn around at 45 pounds, and has been okay with it. I explained to her that this was the safest way to ride and that I paid extra for a seat that would work rear-facing for longer.
She has been forward facing in the other car in a Marathon for well over a year.
No more rear-facing babies in my house.
so if your kids complain about being in a carseat you can tell them you know a crazy lady who kept her seven year old rear-facing.
