I am now over due and think it is about time to put the carseat in. Now, where did you put your toddler and then your infant seat? I can't figure out which is the safest for them. DS is FF and I believe because he is he needs to be in the safer of the two sides, which one is that (driver or passenger)?
Re: Car seat positioning...
Because DH needs the space to put the chair back when he's driving, DD is FF behind the driver's seat. The convertible carseat we have for both kids is very large when RF so DS's is RF in the middle seat.
(DD was just turned FF so we never had an infant seat + convertible seat. We just have 2 convertibles now that DD is FF.)
Oh wow, I never even thought to see if we can move one of the captains chairs. Good idea! We have a Quest though.
DS is RF in a convertible on the driver's side and DD is in an infant seat on the passenger's side. DH and I are usually together if we're out with both children. He always drives and he carries / buckles heavier DS while I carry / snap in DD.
RF is 5 times safer than forward facing for children two and under. Your newborn is more protected by default than your forward facing toddler because rear-facing offers the child more protection than forward-facing does. I understand your hesitation to have a seemingly more fragile newborn outboard as it feels like the more vulnerable seating position, but knowing the safety benefits behind RF over FF, I would put my own FF child in the middle and my baby outboard without hesitation.
