The Reddit co-founder isn't just buying his daughter books, however. Ohanian took to Instagram to show off a mini version of Thor's hammer he got for Olympia, as she prepared to see Thor: Ragnarok.
"Junior's first movie. Mama needed a day off to relax. I rented out the whole theater, so we would be able to just have the family and some friends, the squad and Junior," Ohanian said in the video, before focusing the camera on Williams sleeping on his shoulder. "Of course mama fell asleep," he wrote.
