3 across (infant, 4 y/o, 6 y/o)

[Unregistered]

I have a mid-size SUV and currently have my 7 month old in a graco snug-ride (behind the passenger seat) and then my 4 and 6 year olds in Diono Radians w/the 5 point harness. My baby is pretty big and is ready for a convertible car seat. Should I put him in one of the Dionos and then move my 6 year old (48.5 inches tall, 43 lbs) in a high back booster or should I keep the 6 year old in her Diono and buy the baby in a 3rd Diono or something else that would fit (I have a Britax Marathon, but I doubt it will fit). If I do put my 6 year old in a booster, which is the best one that I can get that will fit 3 across? I already have a graco nautilus and a graco turbo booster--would either of those work? If not, I'm not opposed to buying something better.

I'd try the Marathon right where the infant seat is now first, then between the Radians if needed. You might be pleasantly surprised. If that doesn't fit, try the Radians beside each other, one facing forward, one rear, with the Nautilus. If that fits you won't have to reach between seats to buckle a booster all the time.....not fun!! I'd try Radian, Radian, Turbo last. I really don't like buckling boosters in a tight three across.
