Prevention of mental health problems: rationale for a universal approach.

Background And Objective: Mental health problems are a public health issue affecting as many as 20% of children in modern communities. Risk factors for externalising and internalising problems can occur in infancy. Infants at high risk live in stressed families with parent mental health problems, substance misuse, relationship conflict, social isolation, financial problems or infant temperamental difficulty.

Prevalence, stability, and outcomes of cry-fuss and sleep problems in the first 2 years of life: prospective community-based study.

Objective: To report the prevalence and stability of cry-fuss problems during the first 4 months of life and sleep problems from 2 to 24 months and relationships between the persistence of cry-fuss and sleep problems and outcomes at 24 months.

Methods: The study was a prospective cohort study in maternal and child health centers in 3 local government areas in Melbourne, Australia. A total of 483 first-born infants were monitored prospectively from 2 weeks through 2, 4, 8, 12, 18, and 24 months.
