Child & Adolescent Sleep Service

Sleep is vital to mood, behavior, learning, and healthy child development. Unfortunately, sleep problems are common throughout childhood, and significant sleep difficulties at an early age can lead to sleep problems later in life. At the Child and Adolescent Sleep Service, part of Hassenfeld Children’s Hospital at NYU Langone, we focus on the evaluation and treatment of toddlers, children, adolescents, and young adults experiencing sleep-related problems.

Conditions we evaluate vary by age and include:

  • bedtime resistance and nighttime awakenings in infants, toddlers, and preschoolers
  • insomnia and difficulty waking up at expected times in adolescents and young adults
  • narcolepsy, excessive daytime sleepiness, and fatigue in children, adolescents, and young adults
  • nighttime fears, including fear of the dark and nightmares in preschoolers and school-aged children
  • restless leg syndrome in children and adolescents
  • sleep terrors, sleepwalking, and bedwetting in preschool and school-aged children
  • snoring and sleep-disordered breathing, including obstructive sleep apnea, which can occur in childhood and adolescence

Evaluation and Consultation

Following a focused evaluation of sleep concerns, sleep schedule, daytime behavior, and medical history, we provide your child with an individually tailored treatment plan.

Components of treatment vary based on the problem and may include education about the sleep disorder; referral for a sleep study in cases of suspected apnea, hypersomnia, or narcolepsy; sleep schedule and sleep hygiene recommendations; cognitive behavioral therapy; melatonin or other medications; and light therapy.
