We need a carseat for a big 4 year old who is not used to being in a carseat. Vehicles it will be used in are Dodge and Subaru. Am I better off getting something harnessed even though kiddo is unaccustomed to this or a high back booster?
ETA...
Budget: no more than $150
Vehicles: 2009 Dodge Grand Caravan and 2012 Subaru Legacy
Needs to be narrow enough to sit two teenagers on either side in the sedan.
TIA
