Facebook Is Letting Parents Turn Off Their Kids' Messenger Apps

(NEW YORK) — [f500link]Facebook[/f500link] is adding a "sleep" mode to its Messenger Kids service to let parents limit when their kids can use it.

The company says parents can now specify the times kids aren't allowed on — either as a one-time restriction or something recurring, such as after 9 p.m. every school night.

Facebook launched the messaging app aimed at kids under 13 in December. It comes with a bevy of parental controls and no ads.
