Singing lullabies shouldn't be a problem! On Wednesday, Oct. 7, American Idol alum Kimberly Caldwell welcomed her first child, a baby girl, with her husband, Jordan Harvey

The new parents exclusively tell Us Weekly that little Harlow Monroe Harvey came into the world at 9:37 a.m. "weighing in at a dainty but mighty 5.2 pounds and 18.5 inches long." 

The couple called the delivery "the most intense and rewarding day of our lives."

"We are so grateful to be gifted this perfect little addition into our family," they tell Us. "Can't believe she's finally here and we can't keep our eyes off of her, especially when debating on whose nose she has. So many long nights, memories, and adventures to be made with this sweet little girl and looking forward to every minute."

Caldwell, 33 — who competed in Season 2 of Idol in 2003 — announced her pregnancy back in April, posting her sonogram video on Instagram. She and Harvey tied the knot in Palm Springs, Calif., in December 2014.
