As a mother you will find it very difficult but if you are strong and consistent you can break the cycle.
You need to establish a good routine for settling her and be prepared to hear her cry.
Here is what I recommend when it is nap/sleep time.
Read one short story with her in your lap having a nice cuddle. You settle her down in bed making sure she has her favourite toy/comforter.
Give her a kiss and tell her it's time to sleep, try and be calm and not be ready for her to want you and get upset.
Sing gently 'twinkle twinkle little star' a nice bedtime nursery all the while stroking with your thumb from the top of her forehead down to the tip of her nose. The stroking soothes and also ends up making the eyes close helping them to feel sleepy.
When you have finished a gentle final kiss, quietly walk out of the room pulling the door to, not shut.
Depending on her age you may want to stay in the room not speaking but just gently stroking her forehead down to nose until she falls asleep after the story and creep out.
Which ever one, once you leave the room wait.
If you hear her getting up or not lying down and resting go into the room.
Do not say anything or look her in the eye.
Gently lay her back down, tuck her in and leave.
If she starts to cry allow her to, as a mother you know the pitch it reaches when it is too much, at that point go into the room.
Do not say anything or look her in the eye.
Gently lay her back down, tuck her in and leave.
Keep repeating this.
If she gets too wound up and you can tell that she will not settle and sleep 'in that state'
Go into the room lay her down, do not speak.
Gently shush repeatedly and stroke the forehead down to the nose.
She will calm down and start to feel sleepy.
Then creep out once she has fallen asleep.
How old is she, does she wake up and cry for you?
