“I meannnnn my baby Psalm is so sweet!!!” Kim posted alongside the photo of her grinning and very beautiful baby lying on a linen throw.
The little guy looks to have been dressed by his dad in the sort of comfy sweats that are fast becoming Kanye’s trademark.
Kim’s family and friends – as well as fans – were very appreciative of Psalm’s Instagram pop-up.
“What it do babbbyyyyyy,” sister Kendall responded, obviously weak with affection for her new nephew.
“Little tiny goose bunny,” Kourtney chimed in, similarly besotted.
And who can blame them?
The littlest West is painfully cute and also the spitting image of his toddler sister, Chicago … perhaps with a little bit of Robert Kardashian Snr thrown in.
This photo is a little different from the now-deleted first photo we saw of Psalm. In that photo, the baby was surrounded by cot bumpers and other unnecessary bedding.
Worried fans were quick to point out that this was not a safe sleeping environment, and Kim promptly removed the shot (and hopefully the extra bedding.)
Kim and Kanye’s youngest son arrived back in May with some help from a gestational carrier (although he is the pair’s biological son).
“He’s here and he’s perfect!” Kim posted on Twitter, as she announced her baby’s birth. “He’s also Chicago’s twin lol I’m sure he will change a lot but now he looks just like her.”
While Kim had initially considered calling her baby boy Rob – after her father Robert Kardashian, who a Bali medium told Kim would be reincarnated in her son – they eventually settled on Psalm Ye West.
The name references the Bible (obviously!) and Kanye – who prefers to be called Ye.
The couple were already parents to a bunch of other equally cute kiddos. Daughter North is six, son Saint is three and youngest daughter Chicago is 17 months.
