He is in the Graco MyRide 65 which rearfacing up to 40lbs. He's not quite at 40lbs yet (at 28 months old), but he is tall. He's so tall that it's hard to get him into the car without his head hitting the door frame. As I'm putting him in, he tends to straighten out his whole body and pushes his feet against the door frame so his head hits the other part of the door frame. Even when he doesn't do that (which is rare) his head tends to hit (but not too hard) because he's so long. His head is still about 2 to 3 inches below the shell of the seat, so I guess he can stay facing backwards. But it's irritating because it's so hard to get him in the car without his head hitting the door frame. He's just too tall, but I'm afraid to turn his seat forwards. Even when he's over 40 pounds, I'm still going to be nervous having him ride in a forward facing seat. Anyhow, do you think I should keep him rearfacing until he's over 40 pounds? Thanks.
