The Kardashians have something to celebrate again. The youngest son of Kim Kardashian and Kanye West starts walking.

“My little boy is the cutest!”

The 1-year-old Psalm took his first steps this week and the proud mother was happy to share that with her almost 175 million Instagram followers. She shared some new photos of the boy. “My little boy is the cutest! He just started walking,” Kim also writes.

Psalm was born last May with the help of a surrogate mother. He is the fourth child of Kim and Kanye West. They have two daughters North (6) and Chicago (2) and a son Saint (4).
