The APA is recommending some 41 changes in the area of childhood disorders ranging from learning disorders to retardation (can the APA still use this word?) to the relationship of Asperger's Disorder to autism.
Among the proposed new childhood disorders is one called "Temper Dysregulation Disorder with Dysphoria." This proposed disorder occurs between the years of six and ten and "is characterized by severe recurrent temper outbursts in response to common stressors."
Or in a word, tantrums.
