It sounds like they are actually settling in VERY well for being with you for such a short time.
Just keep interacting with them. The more time they are with and around you for play time in the bath room the more time they will spend interacting with you.
Most gliders will not stay still on you unless it is during the daytime and they are in a comfortable spot to sleep.
At night, the are going to be active. This is their time to explore. You might hid a treat or two in a pocket or on you some how during playtime. They will learn to come and explore on you to find it.
Time and patience will let them learn to trust you and want to be on you more often.
You are doing very well with them so far.
