Mark Zuckerberg Shows Off Homemade Invention That Helps His Wife Sleep Better

“Being a mom is hard”, says Mark Zuckerberg; which is why he had to get creative when it came to helping his wife get some shut-eye.

The Facebook co-founder, 34, revealed on his social media platform that he recently created something he calls the Sleep Box in order to help wife Priscilla Chan, who is a paediatrician and philanthropist, stay asleep at night.

Zuckerberg, who shares two daughters, Maxima “Max,” 3, and August, 1½, with Chan, said the dilemma led him to create a small wooden box that sits atop Priscilla’s nightstand and puts out a dim light between the hours of 6 and 7 a.m.

The father of two noted that the light is “visible enough that if she sees it she’ll know it’s an okay time for one of us to get the kids, but faint enough that the light won’t wake her up if she’s still sleeping.”
