My answer? Yes. Twinsies if you ask me. Logan is on the left in all photos, and Weston on the right.
It appears that I neglected taking photos during weeks 5 - 12ish with Logan (perhaps because I was just trying to survive), but nevertheless, I am starting to notice several differences between them now. There is no mistaking that Weston is all boy - make that man - and it's too funny. We like to call him 'The Professor'.
Here they are with their signature looks of the moment. Logan being...well, Logan. And Weston wide eyed and serious, ha. Perfect harmony.
