Big Girl Booster

I ordered a backed booster to take over to Abu Dhabi for Olivia.  She found it in the garage (I should have known better and hidden it) and continued to badger us until we finally gave in and installed it.  I am not a fan and prefer the tried and true safety of the 5 point harness.  There seem to be too many x-factors with these boosters...make sure the belt is under the arm rests, make sure it is tight, make sure it isn't twisted...  She has actually decided she wants her old car seat back!  Once we get over there, I will be happy to oblige!
