Transitioning my baby from co-sleeping to sleeping on her own?

Make the crib a warm environment. I am not suggesting to put anything in the crib with her. What I do mean is to put on some calming music and gently rub her tommy or head while she is in the crib until she falls asleep. She needs to know that she will be okay without you being there. Right now you are upsetting her normal sleeping habits and comforts. So take it easy and slow. It may take awhile.
