6 month sleeping/standing

Jasmine
I moved her from her bassinet about a month and a half ago because her ability to roll had gotten really good. I looked over to check on her onetime and she had rolled over to all fours and was sleeping. It freaked me out so I figured it was time to ditch the bassinet. I wasn't ready for her to sleep in her crib in her nursery so we switched to co sleeping. That's been fine until now these last couple days i wake up and she standing over me. She is able to 
 pull herself up and hold on to things (started a couple weeks ago). Sometimes she just rolls to her knees and stays asleep like that so I roll her back to her back but it's been a few times that she rolled, pulled herself up( she uses my body) and stands but she still mostly sleeping.  *Edit: my bed is pushed up against the wall and I sleep on the outside so there's no risk of her falling.* I'll lay her back down and she goes right back to sleep. Idk what to do. This makes me even more paranoid to transition her to her crib.
