Questions about sleep – from newborns to teenagers – are among the most common in pediatric practice. A good night’s sleep is in everyone’s best interest for daily functioning and healthy development. Asking about sleep also provides a window into the family’s perspectives on discipline, parental cooperation, family stresses, and views on a child’s developing autonomy.
During their first year, infants may need as many as 18 hours of sleep daily, and the duration of sleep gradually declines thereafter to 8-10 hours nightly in adolescence. Sleep plays an essential role in consolidating memories, attention, and other cognitive functions; the immune system; and metabolism. Additionally, developing healthy sleep habits is one of the first and most profound ways that children learn to expect consistency from their parents, to soothe themselves, and to manage limits. As a child grows, her ability to plan, manage anxiety, and exercise discipline is cultivated through managing her sleep with increasing independence.
Preschoolers who are not getting adequate sleep may have behavioral problems, particularly in new settings (like school) or at transitional times (like bedtime). When a preschooler presents with hyperactivity, irritability, and tantrums, or failure to keep up with developmental expectations, asking about sleep patterns is a good early step. Although sleep disruption may be symptomatic of psychiatric disorders related to mood, anxiety, or attention, before you consider a disorder and treatment make sure that tensions at bedtime and poor sleeping habits are not a major factor.
How do you help tired, stressed parents encourage or enforce healthy sleep habits? Does the family have a routine after dinner that allows a child to settle down (such as taking a bath and then a quiet activity like reading a book with a parent)? Are the parents able to enforce this routine consistently, or does bedtime get dragged out for hours? And if so, why? In addition to ensuring that a child gets enough exercise during the day (but not in the hour before bed), parents will need to turn off the lights at a reasonably early hour so that a child may get adequate sleep before they will awaken with daylight.
Many parents will delay sleep until later as children push to stay awake and play. Sometimes, if both parents work and feel their only time with their children is after they return from work well into the evening, they may want more time with their children or feel guilty about having a strict, early bedtime routine. Reassure parents that even a short stretch of quality time with their children (reading to them, snuggling, asking about their day) is enough to nurture a profound connection.
"Screen time" merits special mention, especially in younger children. Letting children watch television or play on computers in order to "unwind" at the end of a long day is common, but in the time before bed, screen content can be very disruptive to restful sleep. Parents should assess if "screen time" is helping or hurting their child’s ability to fall asleep. Some families have found it helpful to have no screen time (any screen: television, computer, tablet, or cell phone) within 1 hour of lights going out: back-lit screens suppress endogenous melatonin release and can delay sleep. With school-age children, reading at bedtime is certainly preferable to an additional hour of computer time.
It is also worth asking where a child is sleeping. Do they have their own bed? Are they alone in their room? Is their room on the same level of the house as their parents’ room? Children who are anxious may sleep better if they share a room with a sibling or are close to their parents’ room. On the other hand, if they sleep with a sibling who is waking often during the night, they may have disrupted sleep.
It is worth finding out if a child is able to sleep through the night in their own bed. Many children have their own bed and room, but have a routine of sleeping in their parents’ bed. This usually results in inadequate sleep for both child and parents, and a child who does not learn how to appropriately soothe himself. Is it permissible for a child to climb into their parents’ bed in the middle of the night once in a while, if they have a bad dream, do not feel well, or have faced a stressful day? Yes. Is a child arguing to go to sleep in their parents’ bed, refusing to sleep in their own bed, with their parents "giving in"? Then it is a habit worth undoing.
