In the medical treatment of children and teenagers and the accompaniment of their parents, alternative therapies, homoeopathy, anthroposophic medicine, psychology and psychosomatics play an ever greater role alongside conventional, science-based medicine. Ten years after publication of the first edition of this renowned volume, this book has been completely revised for its fourth edition. The updated version presents current developments in the field of epigenetics, answers questions about vaccination, and discusses sun protection and vitamin D. The book also examines newly developed and refined treatment concepts for disorders such as inadequate ventilation of the middle ear, bronchial asthma, neurodermatitis, and ADHS. New case reports have been added, and all drug data have been updated.
