Our son just turned 3 and is rear facing. His Graco 4Ever seat has a rear facing limit of 40lbs (approx 18 kg) with no height restriction bc it’s adjustable. I’ll follow by his weight, as much as I’d love to face him forward and I know he’d enjoy it so much more bc he gets carsick on long rides, I just can’t yet in good conscience.I was going to say…our son was rear facing until nearly 4. I kept him rear facing as long as possible
I know there’s a lot of opinions on the matter but I just did what I felt was safe
If I’m not mistaken they have the Britax OneForLife, which has a rear limit of 50lbs & 49” (approx 23 kg & 124cm)
