The baby pics, posted anonymously on 2channel, may be from her father's company's magazine, published there when she was born. (click to enlarge)
The text says the photos were submitted by 八武崎武 (Yabusaki Takeshi?) of the production department, and the baby is his eldest daughter, Yabusaki Aoi 八武崎碧. This is one more indication that Yabusaki Aoi is Ao-chan's real name. We know now that she is an only child.
There is a quote: "Please, please just don't wake up at night!"
Mr. Yabusaki is a section head in a company, supposedly a game company, and possibly CapCom, the makers of games in the series Monster Hunter, Street Fighter, Resident Evil, etc., etc. No wonder Ao-chan loves gaming, and sometimes plays with her father.
And here is a photo from Ao-chan's blog today, nineteen years later: "A lovely moment in my parents' full real lives."
Ao-chan uses the internet slang リア充 riajuu, "real full," which refers to a happy 3D life.
