3 across in 2009 escape - canada

I am trying to plan how to fit 3 across in my husbands 2009 ford escape. This is our vehicle for towing our tent trailer so it needs to work for longer drives and I am hoping to be able to install once and leave it for the summer. Here's what I am working with

The kids
B will be 4 in June, about 40" and 35 lbs. Recently turned FF
A is 2 , about 34" and 25 lbs, want to keep RF
Baby due in early June, probably average size

The seats
Snugride 22
3 radians ( 1 premier and 2 rxts)
Britax boulevard
Evenflo maestro
Evenflo triumph

I have angle adjusters for the radians and would be able to purchase an infant insert if needed for the baby to use the boulevard. My husband doesn't particularly want a RF seat behind the driver although he has managed with the Snugride there in the past so I think if it was the only way he would be ok.

Also looking for advice on whether the Snugride or one of the convertibles would be easier for the newborn, I do plan to baby wear when possible.

As much as I love playing car seat shuffle it is becoming a bit challenging at this point in my pregnancy so any suggestions and experiences that might help narrow it down for me would be greatly appreciated!

Hello!

I don't know about your vehicle, but am hoping that someone will come along soon who does know.

What is the DOM of your boulevard? If its the newer generation (2010+) you probably could fit it FF next to the RF radian.

The snugride 22 is pretty wide, but you could try a baseless install. If you want a new infant seat, the Chicco Keyfit is pretty narrow and should puzzle well next to the RF radian. If you don't want to spend a lot, the Cosco comfy carry elite is 100$ at Walmart and Target. Its also narrow but I personally never tried it. HTH!
