(CNN) -- Sunday morning feels perfect for Kim Kardashian West to post a photo of her sons.

After all, their names are Saint and Psalm. So why not Sunday, right?

That's just what the reality star and mogul did this weekend.

Kardashian West shared the picture of 3-year-old Saint and 2-month-old Psalm on Instagram.

"Saint asked me to take a pic of him and his brother this morning," she captioned the image, which showed a pajama-clad Saint cradling his baby brother in one arm as the pair appear to be lying in bed.

She and husband Kanye West are also the parents of daughter North, 6 and Chicago, 1.
