'Grey's Anatomy' star Kelly McCreary welcomes daughter 'several weeks' early

"Grey's Anatomy" star Kelly McCreary is a mother.

The actress told People that she and her husband, director Pete Chatmon, welcomed their daughter, Indigo Wren, "several weeks" early, on Oct. 3.

Indigo had to spend time in the newborn intensive care unit of a Los Angeles hospital to "finish cooking" but is now "home and healthy," McCreary added.

"The only thing that went according to our birth plan was that the baby came out!" said McCreary, who added that she'd planned a home birth, but was admitted to the hospital after her water broke. "I was just so relieved that we both made it through safely."

"As stressful as it was to have Indigo in the NICU, it also meant we had a lot of parenting support in the early days," she continued. "We were able to enter into parenthood with a little more sleep and a lot more knowledge than we might have otherwise had thanks to the incredible medical professionals at Cedars-Sinai [Medical Center]."

Now, McCreary, 40, is adjusting to life with a little one. While she admitted that she's experienced "many moments of self-doubt and worry and guilt," the actress, who went back to set to shoot the midseason finale, airing Thursday, noted that motherhood has been "mostly highs."

"Watching all the cute faces she makes as she sleeps, seeing how much joy her very existence brings to the whole family, and all of our friends, even the 'Grey's' crew -- it's such a profound reminder of how much each of us matter just by being here, and that we are not made lovable by the superficial identifiers we attach to ourselves," she said.
