The most likely answer is: Kaiju Capi publicly said he had a daughter in June 2023 , based on an Instagram post saying, “Less than a month away from seeing our baby girl,” from @captaincapi_ and @camryncapito.

What I found

The search results did not show a clear “reveal” post beyond that pregnancy announcement, so the safest reading is that the first public mention was in early June 2023.

Why there’s uncertainty

The wording “had a dau” looks incomplete, and the results also surfaced unrelated Kaiju content, so this may have been a typo or shorthand for “daughter.”

Bottom line

If you mean when he revealed he had a daughter on social media , the evidence points to June 2, 2023.
