Kim Kardashian calls son Psalm her 'forever baby' in touching tribute

Kim Kardashian is commemorating her youngest son Psalm's another trip around the sun.

​The Kardashians star took to her Instagram account on Saturday, May 9, to mark "forever baby's" seventh birthday with a gushing note.

​In the celebratory post, the proud mama shared a series of cozy snaps with Psalm majorly taken on while resting on the bed.

​Kim gushed in the heartfelt note, "Seven years of loving you and learning from you every single day."

​"I’m so proud of how kind, smart, and special you are, and I hope your birthday is filled with lots of Pokeman and dirt bikes," she continued.

​The mom-of-four concluded, "I love you so much!!!! Happy birthday to my forever baby Psalm."

​The carousel began with a cute selfie of the mother-son duo on a train ride, apparently in an amusement park, as Psalm can be seen beaming smiles and Kim is pouting for the picture while both posed by giving a victory sign.

​The other snaps featured a series of Psalms and Kim's bedtime moment, while Kim's other kids also made appearances in the photos.

​She concluded her post with another selfie taken during the sunny time of the day with Psalm and her youngest daughter, Chicago.

​It is pertinent to mention that along with Psalm and Chicago, Kim shares daughter North and son Saint with her ex husband Kanye West.

​As Kim's followers rushed to the comment section to show love and joy over Psalm's special day, the Kardashian-Jenner matriarch, Kris Jenner, gushed over her grandson, writing, "Our little cutie."
