being in your shirt with your scent is very good.
I would pet him/her (wear a loose shirt) while he is in your shirt.
Maybe you could try to get him to sleep in your hand if possible.
I would spend a few days doing this, then you can see how she responds,
if she will sleep or stay around your hand you could try to pick her up and
see how she responds.
at the end of the day, most gliders don't get held in your hand.
Most of mine crawl on my arms or shoulders, groom my hair on back of head,
while in glider room one will sleep in my legs while sitting cross legged.
I will put my hand down with him and he will hold onto my fingers.
at night I can pick up 4 gliders, one somewhat and one just says NO WAY.
but they don't just sit in my hand, they quickly crawl out and start exploring.
sometimes I will put my hand in the sleeping pouch and make them sleep with
my hand, usually several will groom my fingers.
