What is your lighting situation?
Gliders will stay asleep, hidden in their pouches if there it too much light in the room. And it is pretty normal for them to get up, eat, play and go back to sleep and repeat many times a nite.
Your room should be lit during the day and dark at night. The daylight is their cue to go to bed.
I have my cages in the living room and I open up all my blinds every morning and turn lights off now around 11 or 12...they too were not getting up til 1,2 or 3 am. because there are lights on in the living room, dining room and hall ways.
So I have been shutting lights down earlier and feeding them earlier to try to change their schedule. I use a red light bulb in one of my lamps so I can watch them play...it doesn't bother them at all compared to regular white lights.
