“My four-year-old daughter is constantly biting her nails, wakes up in the night with a terrible cry. She cannot be reassured. When is it finally done?, he can't say, why did she despair so. Could it be some kind of neurosis?”
Both behaviors described by you are a symptom of maybe not so much neurosis (it is rather true for much older children), how much too much nervousness. They are an expression of anxiety experienced by the child during the day. Therefore, it would be worth starting the therapy by finding the causes of stress. Your daughter is probably oversensitive and more responsive to rebuke than other children, paying attention (especially in a more severe form), discipline. The negative impact of television programs cannot be ruled out either, computer games on the psyche of a child. So, first of all, you should take care to provide your child with an atmosphere of peace, safety, devotion and kindness.
