I like to sometimes put pouch under my shirt with window facing my skin so he can get a good smell of my scent.
I have gliders that would crab in pouch when I started talking to them, just the sound of my voice would cause 2 to crab, one we got was older and she was bonding very slow. The other was newer and we had not worked with her much given that we had 8 gliders, so she would just crab at my voice knowing I was coming to get her. She now after MONTHS and some bonding lately has stopped most of her crabbing.
Our gliders are awake in the evening and much more active and jumpy if not bonded all the way.
I would also in a week get a glider safe room, sit in the room with them, let them run around and maybe run on you, let them be the first few visits to glider room, after a few visits you can try to pet them. snacks in glider safe room is also a good idea. but don't be pushy, let them have their space.
Give yourself 3 to 6 months, work with them and I think they will come around to you.
