I am trying to figure out the car seat puzzle in my 2015 passat. I currently have 2 radian seats, 1 ffing (2 1/2 year old) and 1 rfing (10 month old). I am due with baby #3 in March and currently have the cybex aton, which does not fit between the 2 radian seats. If I turn both ffing it is a tight fit, but I really would like to keep my 10 month old rfing as long as possible. I tried putting the ffing seat between the rfing seats but wasn't able to get a good install and worry about being able to buckle in my oldest. Is there another/better option for the baby coming in March? Anyone not use a bucket seat for their third child (I like to wear my babies while they are young so I rarely carry the seat with me)?
