Rocco's a big bro! CaCee Cobb and Donald Faison have welcomed their second child together. The mom of now two announced the news via Instagram on Friday, April 24.

"Meet the newest love of our life, Wilder Frances Faison," Cobb, 37, captioned, introducing her daughter for the first time. "#babygirl." Still at the hospital, the newborn slept while bundled up in a white blanket.

Cobb announced in October that she and the Scrubs alum, 40, were expanding their family. The couple, who wed in December 2012, are already parents to 20-month-old son Rocco. (Aka, the best friend of Jessica Simpson's son Ace!)

While awaiting Wilder's arrival, Cobb was the guest of honor at a baby shower last month. "Words can't even describe the amount of love that went into this day," she captioned a photo of the Pinterest-worthy table setting via Instagram. "Thank you @jessicaSimpson - my heart is full. #babylove."
