Messenger on my daughter's ipad

[Baumsc]

My daughter keeps getting messages from her friends after bedtime. Is there any way to turn it off at a certian time. She likes to keep her ipad with her for an alarm.

If she is running a reasonably recent version of iOS (8 or later) have her check out Settings > Do Not Disturb.

Is there any way to set a time on the do not disturb so it starts at her bed time

Yes, go to settings, do not disturb, scheduled. Set the times you want and it is done.
You should check to see that the alarm that she uses still works with do not disturb on, alternatively, turn off do not disturb before the alarm is due.
