Helping Children Who are Anxious or Obsessional [PDF ebook] 
A Guidebook

This is a guidebook to help children who: are insecure or worry too much; suffer from phobias or nightmares; find it difficult to concentrate to let go and have fun; have suffered a trauma; are worryingly good or seem like little adults; use order and routine as a way of coping with 'messy’ feelings; retreat into dullness as a way of managing their being in the world; and, develop obsessive-compulsive behaviour in order to ward off their too-powerful feelings.
