Kim and her husband Kanye West welcomed their son back on December 5, but had not released any images of the infant’s face until now.
Kim previously teased fans by sharing a photo of Saint’s hand clutching the finger of his big sister North, two.
Kim captioned it: ‘She said “He’s my best friend.”‘
Their reticence when it comes to Saint is perhaps a surprise for the fame-loving pair.
Indeed viewers of Keeping Up With The Kardashians were given an insight into every moment prior to Saint’s arrival, from Kim’s distress over her initial failure to conceive, to her breaking the news of a positive pregnancy test to her family, to the moment her waters broke.
