WATCH: Serena's baby goes to the movies for the first time

Parents get to enjoy watching their children hit a lot of milestones, like their first tooth, first steps, first day of school, etc. In the case of Serena Williams and Alexis Ohanian, they got to take Alexis Olympia Jr. to her first private movie at two months old.

The new family went to see the action flick Thor: Ragnarok in a rented out theater.

Junior falling asleep was to be expected, but Williams also couldn't keep her eyes open (no offense to Chris Hemsworth, of course).
