When the Camden twin boys Sam and David were introduced to the show in the middle of season three the "7th Heaven" crew used quadruplets (Zachary Brino
, Lorenzo Brino
, Nikolas Brino
, and Myrinda Brino
) to play the twin babies as they rotated them around between scenes due to Child Labor Laws and the amount of time one set babies could be kept under lights and camera. But as the twin characters became older the producers decided on using one pair of the quadruplets, Lorenzo and Nikolas, especially since one of the quadruplets was a girl. Beginning from season six both boys had the roles permanently of Sam and David Camden and then appearing in the opening credits of the show. See more

See my tummy? That's you.
Maybe I never should have come out.
But... look what you would've missed... riding on Daddy's shoulders... and Simon rocking you on the front porch... and Mary... giving you a bath in the kitchen sink.
My butt was a lot smaller then.
All of our... bottoms were a lot smaller then.
