My son is 7 months old right now. We've recently installed our True Fit in my husbands VW Jetta and are about to install in in my Honda Civic, but I have a question about the recline angle. It seems to be reclined even more than the infant seat was, is this correct?? The line on the seat is parallel to the ground as it states it should be in the manual. Also, how long must it be reclined this far? At any point can we make it more upright?? Thanks in Advance.
