We currently have our 3yr old (almost 30lbs, almost 3ft) rear facing behind the passenger seat in a Diono radian rxt. We are due with #2 in a couple of wks and the baby will be in the Graco clickconnect 35 that we used when my son was an infant. I’m wondering if I will need forward face my toddler in order to rear face my infant in the middle. Also wondering which connecting (latch vs seatbelt) is best for both as I can only latch one of them if the middle seat is being used. Or would it be best to outboard them both? Any guidance is appreciated! My husbands vehicle is a 2017 Volvo XC 90, same questions would apply.
