Today when we were in the car I put my hand on his seat and I felt his head. I glanced at his seat and noticed he doesn't have much room left until he is ready to be turned around. I think his head is about 2 inches below the shell. It could be more or less; it's hard to tell since his hair is so fluffy.
He's currently about 32 lbs. I was hoping to RF him til 40 lbs but it looks like we'll hit the height limit before we hit the weight limit. I'm going to head out there with a measuring tape when I get some time and see just how much time we have left.
Did anyone else have to turn their kid before they planned to?
