shared some exciting news about her and ‘s youngest child, Psalm West: the 1-year-old has officially taken his first steps! On Friday (June 12th), the reality star shared some adorable photos of her cuddling with her baby boy, who just celebrated his first birthday last month on May 10th. In the photos, Psalm can be lounging in his mama’s lap, but according to the caption, she won’t be carrying him around all the time much longer. “My baby boy Psalm is the sweetest!” Kim wrote. “He just started walking!”

Kim and Kanye welcomed their baby boy last May, after he was born surrogate. Psalm is their second son after older brother, Saint, and the youngest of their four kids. A few days earlier, Kim shared a rare shot of all four of them on Instagram looking as adorable as ever. In the sibling portrait, oldest sister North has her arms around baby Psalm, while two-and-a-half-year-old Chicago sits next to them. Saint flashed a peace sign at the camera while smiling wide.

Last week, Kanye celebrated his 43rd birthday on June 8th.  and thanked him for “always being you and never letting the world change who you are.”
