I had this stroller and from my memory the infant car seat adaptor only clicks in a certain way so the car seat is always facing you. However if you put the carseat in the front most seat position and then put the other regular seat (closest to the parent console) facing the infant car seat they would be facing each other.
It says to use the car seat adaptor until 6 months old, but my DS was a big baby and sitting up around 4.5 months and we started using it around then. It comes with a head support for each seat so I put that in there too and had no issues.
