She was close to you for 9 months or so and now you want her to detach from you? It is not that easy. She is use to your sound, movement, moods, etc. and she is not ready or capable of releasing you. At this time in her little life, it is all about her. You have an unique bond with her and you can't just break it at the moment. When she sleeps, you should be sleeping as well to get your rest. Take it from me, you can not go without appropriate sleep and expect to be able to give her your all. Be bless and much success.
