I don't think it's bad that she sleeps with you : ). If it works for you both that is great. If you really want her to sleep in her own room do it gradually. Maybe give her a t-shirt or something of yours to snuggle with. I would read to her and cuddle her in her room and let her fall asleep there... then if she comes into your room, you can take her back. Some kids just are this way - my 5 year old still comes in 1/2 the nights... I agree with S.H. and just try to enjoy it... I know there will be a day she "doesn't want me around".
