Kim Kardashian shared a photo of her infant son Psalm West on Instagram on Monday. The sleeping baby is pictured wearing one-piece, white pajamas. His arms are bent and his head is resting on his hands. The "Keeping Up with the Kardashians" star's third child with her husband, music mogul Kanye West, was born via surrogate on May 9.
