I drive a Ford Focus wagon. dh a Nissan SUV. In my car, DD1 (age 5) has a Radian ff in the middle seat, DD2 (5 months) an infant Chicco keyfit 22 on the outboard. The kids mostly ride with me in the car, however once I return to work in the fall, they will be riding in both vehicles. We also have a Britax Marathon for DD1 in my dh's SUV. This Britax also fits in my ford focus (with the radian and chicco)...allowing me to transport one of DD1's shorter friends if needed.
DD1 is about to outgrow the Britax Marathon (which will be passed on to DD2....we think...) and we would like to get her another seat to use in dh's vehicle. So I was all gung how about the new Britax Frontier and it's super tall harness slots....and I tried my friend's in our Ford Focus wagon next to the radian and the chicco (hoping I could fit it in and be able to transport 3 kids!). Unfortunately, it did not fit and I could not close the door! It's freakin huge!!! I really want to keep the radian in the middle seat...as it allows for a seat and passenger on either side (the Britax doesn't) and it's a PITA to move.
So....I don't know what to do. Options include:
1. Buy another radian (but it will probably be outgrown in a year or 2)
2. Buy the Britax Frontier (and lose the ability to have 3 in the backseat of either vehicle) and be in a 5 point harness longer
3. Buy a high backed booster with narrow profile. DD1 is generally pretty cooperative and safety conscious (she ensures her harness is bucked tightly and correctly. She doesn't normally fall asleep in the car anymore.
Is there any evidence that beyond age 5, that 5 point harnesses are safer than boosters?
If you'd go for a booster, please suggest a brand that's on the narrow side (my kids are long and lean). I'm a rookie to boosters!!!
I'm losing sleep over this. Thank you!!!!
