I was in the same boat when I bought my pastel. I had held a few BPs, babies and adults, and then when it came time to hold my own after she had been home I kinda freaked out a little inside.
Here's what I did. I pulled her hide off of her to let her know I was there. She just stayed all curled up, and I just sat there. I would wait until she felt comfortable enough to start moving around and flicking her tongue, then I would scoop her up. Once she was in my hands I just kinda let her do her own thing. After a few times of that, I was as confident as Mighty Mouse!
Hope this helps!
