I didn't need to hug my bb for her to sleep since she was 5-months old, I tried to establish a set of behaviours before sleep for her to adapt.
1.same time of the day, give her a bottle of milk;
2.sitting on my big bed first playing with some familiar sleeping toys, which allows her not to resist the bedroom;
3.listen to the music box for several times, then she will be more relax, and she will 打呵欠if she is real tired;
4.put her in her bb bed with one toy in hand;
5.talk to her that she must sleep because she is tired and she is a very good child if she sleeps;
6. put a blanket on top, then she will close her eyes.
The first few days will be difficult but you must be firm on not hugging her, and it will easier if your bb has a regular play and dining schedule during day time, because bb will follow routine mode of living, sleeping habit is one.
hope it can help, if this cannot help still, you can pm me and may be we can have phone call directly.
