I would go the nightlight as a start. The light in Steph's room has a dimmer, which stays on all night (unfortunately I don't think most flouro globes are suitable for dimmer switches). I think it keeps her happy, she can see her room if and when she wakes during the night, so she can keep her bearings. If DD says there is a bear or a lion or whatever, turn the light up, open the cupboard, some drawers, etc, and 'show' her there is nothing there. Some children don't like it when their toys 'look' at them, so maybe if she has lots of dolls or animals that face the bed, turn them in a different direction.

Would also suggest a bedtime toy, if DD hasn't got one already? Steph has a few toys that she really likes, and she takes one to bed with her. She can go to sleep without, but she likes to cuddle up with something sometimes, so its part of our bedtime habit. A toy may help her feel more secure? Maybe if you tell her something along the lines that ted bear (or whatever its called) will keep her company all night, and be there for her to cuddle if she needs to or has a bad dream, or something like that.

I'm not sure what else to suggest. Its hard not to just take them into your bed, especially in the middle of the night when you have been sound asleep yourself. I made that habit with Steph when she would wake in the early morning, but have managed to get out of it.

My Dad's new wife used to be a nanny, and if her charge' would scream, she would tell them that the baby birds are sleeping, and that their screaming will wake the baby birds. That might work? I tell Steph that Daddy and all the lizards and fish are sleeping, but I'm not sure if she pays it much attention. I think the words 'Daddy', 'lizards', and 'fish' get her attention more than anything.

Best of luck, and I hope that something there helps.
