We attempted to install them this weekend...wow, are we inept!!! Luckily it ended with no temper tantrums (for us, not DD - she was napping during the debacle). Unfortunately it also ended with us leaving the seat installed to the best of our ability (read: not very well at all) in the center seat and us re-installing the base on the drivers' side so that I can call and have them 'inspect' (read: install) the convertible for us. Major parenting fail!!
Re: Operation Convertible Carseat: FAIL!
Oh yeah...we won't be taking them out anytime soon after they're installed correctly...and not just b/c DD is nowhere near close to the 20 lbs. she needs to be anyway.
