I have Quilt and Huggy, my teddy. Quilt is folded under my pillow and Huggy is sitting on my side on the floor. My teddy's just the right size to wrap my arm around, like a body pillow. I can grab Huggy when my husband's not in bed with me and I can pet Quilt easily if I need the soothing. My husband even has a favorite pillow case. It's a texture thing, we like the way the pillow case and blanket feel. I've had Huggy since birth, Quilt has been various items through my life. First I had a Holly Hobby blanket, at some point my mom decided I was too old for it and put it away, so I adopted a bed sheet that felt the same, then a quilt that a cousin had left at our home at one time and never reclaimed.
My Daughter has Panket (a mash of Pink and Blanket), it's harmless, if she was sucking her thumb then I might object and try to wean her from that, but Panket, no big.
Also I was a thumb sucker, I have an overbite because if it. I've been told I still do it from time to time in my sleep!!
