DD has been telling me for a few weeks now that she's scared of there being a fire in the house. first it was just a general concern that she had and i tried to explain she was safe and what to do in case of a fire and showing her the smoke alarms etc. then she woke up with nightmares about fires. i banned her from watching fireman sam when it was on cbeebies a while ago as it made things worse. last weekend she said a few times that she was "fed up of thinking". when i questioned what she meant she said she was fed up of thinking and dreaming about fires. she's so genuinely upset about it all and i feel a bit helpless. how can i make her feel safe and stop her worrying about it?
