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. 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.
