For fun, I put Sam in the same outfit Jack wore in this 3 month photo. Can you tell who is who?
Ok, the extra hand going "Boop!" gives it away.
They actually aren't that different. I know Sam is humungous for his age, but Jack was big too. And the difference is just an inch or so. I think Jack had more limbs, and Sam more belly. But both boys are big and perfect!
