The actress delivers her third child with actor Nathan West

She’s merely a few hours old, but Chyler Leigh’s third child is already displaying one talent – impeccable timing!

Leigh, 27, and her husband, actor Nathan West, 30, welcomed their daughter Anniston Kae just seven days after Leigh wrapped filming Grey’s Anatomy‘s fifth season, Leigh’s rep tells PEOPLE exclusively. “Both mother and child are healthy,” he says.

Anniston, who weighed 7 lbs., 1 oz., joins siblings Noah Wilde, 5, and Taelyn Leigh, 2. And the family hasn’t ruled out the possibility of more children in the future.

“We love our family,” West told PEOPLE in November. “If I wasn t working as much and [Chyler] didn’t have the show, we’d have five or six kids.”

“[Chyler] is a phenomenal actress and an amazing best friend, but hands down, mothering is what she does best,” West added.

The couple, who met at a pilot audition 10 years ago, will celebrate their seventh wedding anniversary later this year.
