Gently pick them up. I usually scoop them up with both hands, and just let them either sit or walk from one hand to the other. Do this once a day, and they will lose the fear.
Had babies and juveniles jump hazardously off me. Best advice i can give you is just let them be at their own pace, seeing you every night and just patiently wait for them to grow up as they lose the flighty attitude when they become adults (well a great majority does)
