|Kayla Colbert and Rylie Colbert|
|Episode||Unplanned Parenthood, others|
Rylie Colbert and her identical twin sister Kayla Colbert, were the two-year old actresses who played Lisa Cuddy's adopted daughter Rachel Cuddy in Season 7. It has not been revealed who played Rachel in seasons 5 and 6 as an infant. Because of child labor laws in California, twins are usually picked to play characters under a certain age to allow a longer shooting day as actors this young can only be on set for a limited number of hours each day. The Colberts showed a good grasp of dialogue, take special direction well, and have shown an ability to interact with the other characters well.
