I've got a 3 door rav 4 and was wondering which seat will be best safety wise to pop the car seat on? either back or passenger? will be alot easier for me to use passenger. ( can see baby and won't have to climb into back) i know i'll have to get the airbag disabled if i go for passenger side. Plus i've got curtain side airbags in front and back do you need to get them disabled aswel? Sorry just one more question but when i tried the car seat the other day it wasn't totally stable there was a bit of movement.. is that normal? Thanks for your replies in advance xx
