My 3.5 year old is petrified of monsters in our house. This isn't a nightime/bedtime issue, she is scared in the daytime. She won't go into the kitchen or upstairs on her own and today she was climbing the stairs (I had to be behind her) and she was screaming she was so scared. Despite my assurances that she is safe, she remains scared. It seems to have come from nowhere... Does anyone have any tips on how I can help her get over her fear please?
