1. I’m 6’1″ and my doll is165cm. The trick is to bend her at the waist. Lay her on her side. Knees up. One hand on waist, the other lifts her by the neck. Less pressure on her shoulder. More room for your arm under her neck.
2. If you setting your doll on its side the whole night, it might do some damage to the TPE or silicone over time. Don’t even think about laying on its arm, it’s kind of fragile. You can drape one of the doll’s arm over and on top of you when you sleep or cuddle.
