Mark Zuckerberg says he invented a 'sleep box' to improve his wife's slumber
- pxeboot 8y agoHasn't this existed for years? We had a light like this for our children to help them sleep through the night. Actually worked really well.
- runjake 8y agoRead the article. It's not a night light to help them sleep. If the light is on, it's betwen 6-7am and they should get up. If the light is not on, they can still sleep.
