Car seat placements

Taylor

Currently my 20 month old is in a Graco 4ever which is pretty big, rear facing. I’m due in June with new baby and have another Graco 4ever but will most likely start out with our infant seat (Chicco Keyfit). Should I move my older daughter over to passenger back seat and put the new baby behind me? I don’t think it’s plausible at all to think baby could fit in the middle properly so just need to know which side would be better. Convenience wise I’m thinking behind my driver seat and then can visually see my 2 year old on passenger side would work well but open to suggestions.
