• Play a continuous-play tape recording of her favorite lullabies. The same lullabies she hears going to sleep is what she will hear when she wakes up.
• Teach her some self-comforting skills, such as if she has a special attachment object, such as T-bear. Put her fuzzy bear close to her (if she's not allergic to dust), so when she wakes up she can cuddle T-bear.
  
  

The reward system you proposed is a good one. Sometimes rewards are necessary to break a fearful cycle and show the child that she really can sleep in her own room throughout the night. Once she gets a sense of this accomplishment, that becomes its own reward. If none of these tactics are working, take it as a temporary stage of nighttime anxiety she is going through and make the following deal with her. Put a futon or mattress at the foot of your bed and market it as her "special bed." Tell her that she can come in and sleep there when she wakes up if she wants to with the provision that she "tiptoes as quietly as a mouse, slips into her special bed, and doesn't wake up mommy and daddy." With this arrangement you accomplish two goals of nighttime parenting: you get you and your husband an uninterrupted night's sleep and provide nighttime security for your child until she reaches an age when she can comfort herself at night. Above all, realize you didn't create this nighttime anxiety. Without the early attachment she received, her nighttime anxiety would probably be a lot worse.
