Not the same kid but some more context about how he views his children

St. Clair first met Twitter owner Elon Musk on X, formerly known as Twitter, in 2023 and began exchanging direct messages with him.[4][3] She gave birth to Musk's son in 2024.[11] Musk was not on the child's birth certificate and had been unresponsive to St. Clair's messages despite previously acknowledging paternity in writing. Musk met their son on September 21, 2024, and spent two hours with him, followed by one hour the next day, then met him again for 30 minutes on November 30, 2024, and continued texting St. Clair thereafter.[4]

He sent this to Grimes back when they were fighting publicly a few years back and she claimed he'd kidnapped them or something like that. Anyways, you see the other kid passing by him just out of frame. Nah, it comes off as an irresponsible d-bag when he does it. Considering he doesn't see them very often as it is and that this was sent ti taunt Grimes cause he hadn't returned them by the end of his arranged visitations.
