We have not done this, and it's on my list of things to do. Hopefully in the next week or so, I know it's important to get it done since so many things can be overlooked. I'm fairly confident they are installed correctly after reading over the manuals and doing research but I can never be too safe!

Did you have your car seat checked for proper install? When you took it in to get it checked did you learn anything that you were doing wrong? Where did you take it?
