users, however, thought they cracked the code, believing the young mom named her second-born child Jacob.
After one user posted the video to the platform, several eagle-eyed fans jumped in with their theories on the baby's moniker.
One person confidently wrote: "Kids called Jacob," theorizing Kylie's song choice hinted at the 3-month-old's name.
Another had the same thought, questioning: "Could the baby's name be Jacob?????"
NOT ADDING UP
The post also raised eyebrows as viewers questioned the authenticity of her ultrasound video.
One user took to the platform to comment on inconsistencies in the clip and the information Kylie shared about her baby boy.
One suspicion the fan pointed out was that the name listed on the top left of the ultrasound was "Crissy" instead of the beauty mogul's name.
They also noticed the date on the video was July 28, 2021, with a gestational age of 23 weeks and three days, despite Kylie giving birth six months later.
The skeptical fan theorized "there is no way on earth" that the makeup mogul was that far along in her pregnancy when the ultrasound was taken.
"All this combined with the fact that she won’t show his name or face? It’s pretty, pretty weird," they added.
Others agreed, questioning the timeline of the Keeping Up With the Kardashians alum's pregnancy and delivery date.
One user commented: "this would have made her due 11/21/21."
Another noted the tot's unique birthdate: "I never thought that was her son’s real bday, I think he was born earlier and she wanted his bday to be 2/2/22 so she hid him til then."
Meanwhile, some loyal fans thought the star used a "fake name" or her middle name, Kristen, to explain the different moniker on the ultrasound.
'DIDN'T FIT HIM'
Following Kylie's announcement of the name change, sources claimed she and Travis weren't keen on the name Wolf after spending some time with him.
Advertisement: "Kylie and Travis liked Wolf, but after getting to know their son, they felt like the name didn't fit him.
"They wanted to choose the perfect name that they both loved."
The source added that Kylie will "share his name when she's ready."
Fans were convinced that her decision was due to her former friend Tammy Hembrow accusing her of copying her 6-year-old son Wolf's name.
The TV personality hasn't addressed the alleged feud between them.
Kylie and Travis are private about their personal lives as they didn't reveal the 24-year-old was expecting their first child until their daughter's birth.
They also haven't unveiled their newborn son's face yet, only posting photos and videos of his feet and hands on social media.
