Information Overload

I have been researching, reasearching, and more researching convertible car seats for princess for days and finally I am so overloaded that I think I am more confused than I was originally. Its such a important, big decision. I am looking early tho, so I could take a break for at least a week but when I start something I like to get it done and then move to the next project. I will probably overloaded myself more. I open to any and all suggestions at this point. I put up all my info including cars we own, her size, what she is in now, and how she likes to look out the window on to boards and have got barely any responds or suggestions. Ugh. Well on to do more of the same.
