Do you know what it is she is frightened of? Hard in a two year though. Sometimes when DD1 decides there is a dinosaur in the cupboard/under the bed etc, we have a little session yelling at them to go away, their mummies are looking for them and to go and sleep in their own beds. We really yell it to. Works every time.

I wonder if you can still get the touch activated lights that ran on batteries, or a very low glow solar powered garden light you can leave outside during the day to charge.
