I just found out about this new seat: the Graco My Ride 65. It is Rearfacing to 40 lbs (Yes, 40!!) and Forward Facing from 20-65lbs with the harness. It also comes in a pretty pink and brown.
Its basically the convertible "sister" seat to the Graco Nautilus. Where the My Ride goes Rearfacing and Forward Facing, the Nautilus is Forward facing only, from 20-100lbs. The harness on the Nautilus, like the My Ride, goes up to 65lbs.
I do think its cool that the My Ride supports extended rearfacing up to 40lbs (although, the height of a child could make a difference in how long you keep it rearfacing). We have decided to keep Hudson rearfacing until he's at least 2... I've read a few articles on 2 and 30 is the "new" 1 and 20. Children who are turned forward facing at a 1/20lbs have a much greater risk of spinal injuries and internal decapitation from the force of whiplash. Here is a great site regarding rearfacing into toddlerhood: http://www.car-safety.org/rearface.html
Anyhow... just got a carseat kick after reading Ashley's blog about her daughter's booster seat. I came across the new carseat on Carseat.org and thought I'd share it!
