Yet fans have raised concerns for the newborn.
WATCH BELOW: This is how the Kardashians celebrated little Psalm - and yes, it was VERY glam.
Kim took to Twitter to share the very first photo of her son.
On May 17, she tweeted: "Psalm West."
It was attached to a photo of a screenshotted message from Kanye that read: “Beautiful Mother’s Day With the arrival of our fourth child. We are blessed beyond measure We have everything we need.”
The 41-year-old dad included a photo of his child, sleeping in a crib.
Some fans have since warned Kim about the danger of SIDS (Sudden Infant Death Syndrome) that come from the baby's crib.
WHAT IS SIDS?
The Mayo Clinic has explained, "Sudden infant death syndrome (SIDS) is the unexplained death, usually during sleep, of a seemingly healthy baby less than a year old. SIDS is sometimes known as crib death because the infants often die in their cribs."
“Please please please go pay an overpriced ‘sleep consultant’ to get all that unnecessary padding, bumpers, and blankets out of your child’s crib so they are not at risk for SIDS. I’ve tried and failed to resuscitate too many children that have died this way,” one person tweeted.
Adding, “Signed, an ER doctor.”
Another remarked: “1. Congrats! 2. Anyone else freaking out about all the blankets & bumpers?! American Academy of Pediatrics recommends keeping the crib free of blankets & pillows until baby is 12 months old, as these can create a suffocation hazard. @kanyewest Just looking out for a fellow dad.”
