I am looking for a convertible car seat for my 13 month old daughter. She has just out grown her chicco keyfit infant seat by height. I have a 2011 dodge charger that i will have 3 across in te back. A 6 yr old in a booster, a newborn in the chicco keyfit and this convertable. I know some seats will last longer than others but thats a non issue beacuse my kiddos are tall and i plan on switching from the convertable to a booster seat when the time comes, so it doesnt need to last forever. I am trying to decided between the new chicco nextfit convertible and the britax pavilion. Which do you think is better/safer? Thank you in advance for you input.
