When I brought my girl back to visit my mother, she will be put into a yaolan. At home, I never install yaolan so my girl will sleep on the bed or cot. She is flexible.
For a 1 month old, I am sure you can still teach your baby good sleeping habit. Try to turn her side way and pat her but once she falls asleep, stop patting her. There is one kind of sleeping bag that looks like a wrap around. You might consider using that as it could create a sense of security - your baby might be thinking that you are carrying her.
