Doting grandmother Kris was also one of the first members of the family to share a birthday post on her own Instagram account. Alongside a collage of photos of her grandson, the momager wrote: "Happy Birthday Saint!!!! I can hardly believe you are 4 years old!!!! You are growing up so fast... you are such a sweet, funny, kind and amazing boy and I love seeing your sweet face and beautiful smile. You bring such joy to everyone around you!! I love you Sainty."
The reality star shares her four children with husband Kanye West. While Kim has said that she and her husband would love more children, she has recently admitted that since having her fourth baby, her brood now feels complete. On an episode of Keeping Up with the Kardashians, which aired in October, Kim spoke to her family about her brood and told them that she was "done" having more children. "Our surrogate is so amazing, she had the easiest delivery," she said. "She pushed literally maybe one time. Kourtney and Kanye were in the room with me. I feel so complete." The doting mum added: "I really do feel like four [kids] is the perfect number for me. I feel so full in the best way, but I'm done."
