Sleep problems in early childhood may be linked to the development of certain mental health disorders in adolescence, according to new research.

A study of 7,155 children in the United Kingdom found that waking up frequently during the night and irregular sleep routines as babies and toddlers was linked to psychotic experiences in children ages 12 and 13. Also, children who slept for shorter periods at night were more likely to be associated with borderline personality disorder at ages 11 and 12.
