J.R. Smith is experiencing one of "the greatest days" of his life, thanks to his 1-month old daughter, Dakota.

The Cleveland Cavaliers star got to hold Dakota for the first time on Monday after his wife, Jewel Harris, gave birth to her in January five months premature. Dakota weighed one pound at birth.

"Today is one of the greatest days of my life," Smith, 31, Instagrammed alongside a picture of him holding his baby girl to his chest. "Today I get to hold my youngest for the first time! GOD is GREAT! #DakotaStrong."

Last month, Smith and Harris emotionally told fans that their newborn daughter was born five months early in a video posted by Uninterrupted. They share two other daughters, Demi and Peyton.

"She's five days old today, her name is Dakota, and she weighs one pound," Harris said, on the verge of tears. "We know we're not the only family going through this, who has been through this, and who will ever go through it, and that's why we decided to share what we're going through with you guys. Please keep us in your prayers, and we'll do the same for everyone else."

Since then, the family has been at Dakota's side in the hospital. Smith Instagrammed a sweet picture of Demi looking in on her little sister last month.
