Facebook’s Zuckerberg builds his wife a glowing ‘sleep box’

Zuckerberg has two daughters with his wife Priscilla.

Mark Zuckerberg said he built a glowing wooden box to help his wife Priscilla sleep better through the night without having to check her phone to see if it’s time to look over their children.

The "sleep box” emits a very faint light between 6am and 7am – when their daughters are expected to wake up.
