Healthy sleep habits promote
  1. Optimal functioningHealth, development, learning
  2. Positive mood. – Happier baby or toddler, happier parents, family well-being
Babies can be helped to develop good sleep habits
  1. Establishing healthy sleep habits early can prevent sleep
  2. Babies/toddlers don’t just outgrow sleep problems
  3. Positive outcomes on interventions for early childhood sleep problems

Establish a Bedtime

Bedtime routine

  1. in room where child sleeps
  2. low lighting
  3. quiet, soothing activities
    music, reading
  4. no TV

Promote Positive Sleep Associations

  1. (Babies develop sleep associations early 8-10 weeks)
  2. Consistent, soothing bedtime routine leads to sleep associations : Same time, same place, same activities

Limit the bedtime routine to ~30 minutes

  1. The Transition to Sleep
  2. Eventually end the bedtime routine ends by placing infant in crib on back drowsy, but awake
  3. No napping 1 ½ – 2 hours prior to bedtime

If old enough, give baby a transitional object

  1. special blanket,
  2. mom’s t-shirt,
  3. or other soft object infant can use to self soothe & be reminded of mom

Benefits of Bedtime Routine

  1. Promotes self soothing
  2. Baby/child learns how to transition to sleep without having to rely on external help
  3. Helps babies maintain sleep

Night Wakings

  1. Normal part of sleep
  2. Self-soothers & Signalers
  3. Associated with how the child falls asleep at bedtime
  4. Child will seek the same activities to transition back to sleep in the middle of the night (e.g., rocking, feeding, parent’s presence

Night feedings. Typically not physiologically necessary after 6 months

Some babies, however, settle into the newborn sleep routine dreaded by many expectant parents—the so-called day-night reversal.

As the description implies, newborns are known on occasion to mix up their days and nights.

These temporarily backward-sleeping

  1. babies often begin to increase the amount of sleep they get each time they go to sleep according to plan, but simply do so more during the day
  2. while demanding to be fed, changed, and entertained throughout the night.

As painfully exhausting as this upside-down approach to sleep may be for those of us accustomed to getting most if not all of our sleep at night, the assurance that this too shall pass once again comes to mind.

We can all but guarantee you that hope is not far away.

In most instances, the fact that your newborn is learning to replace lots of short little catnaps with longer stretches of sleep

  1. whether they happen to fall during the day or at night—
  2. bodes well for a more “civilized” sleep routine in your not too distant future.

Lights On, Lights Off

If your baby seems determined to-

“play” during the night

and sleep during the day

there’s really no quick fix,

but there are some easy things you can do early on to set the stage for more acceptable sleep habits in the future.

During your first few weeks at home with your baby, try to establish an atmosphere that clearly differentiates night from day.

A good night’s rest may not result overnight, but this approach can help get you there sooner.

  1. Allow for active sleep. During the day, don’t worry if your baby falls asleep in more “active” areas of the house – in rooms with light or music on, for example. Similarly, don’t be afraid to run an occasional daytime errand, even if this means your newborn may not quite make it all the way home before falling asleep.
  2. Consistent contrast. Don’t spend much time worrying about background noises such as talking, telephones, or music during daylight hours. In contrast, try to make your nighttime interactions calm and quiet.
  3. Maintain focus. Whenever possible, take a more focused approach to your nighttime interactions

limiting them to feeding, burping, changing, and gentle soothing when necessary.

Soft-spoken approach. Get in the habit of taking the aforementioned measures

  1. in a dark room using a soft voice
  2. whenever you want to signal to your newborn that it would be a fine time to sleep.

Why do so many newborn infants have night and day reversed?

Many newborns confuse day and night because babies in-utero typically sleep when the mother is moving around during the day and wake up at night. When a baby has night and day reversed, he or she will not only be awake more at night, but will also do more of everything — eat, excrete, fuss and need attention. When finally sleeping, the baby may be easily disturbed.

How do we know night from day?

We all have light-sensing cells in our retinas that communicate with the part of the brain that controls our diurnal rhythm, or biological clock. To take advantage of this natural rhythm, make sure your baby is exposed — with eyes open, if possible — to bright light during the day.

How can I help my baby adjust to a normal night and day pattern?

During the day:

  • Do not swaddle so that the baby wakes more frequently. Dress the baby warm enough that he or she will not need extra blankets.
  • Place the baby’s bed by a bright window (although not directly in the sun).
  • Avoid steady background noise (like music) as this will encourage the baby to sleep.
  • Avoid activities that put the baby to sleep. 
  • If you take a break during a feeding (to burp the baby or change the diaper) see if the baby will spend some time being social with you before you complete the feeding.

In the evening:

  • Gently try to keep the baby awake and feed him or her as often as possible.

At night:

  • Swaddle the baby securely. You can buy blankets specifically for swaddling to make this easier.
  • Consider having the baby sleep in the car seat (or similar infant seat). A small and cozy space will help the baby feel secure. 
  • Try to avoid overhead lights. 
  • Music or other steady white noise is helpful, especially simulated in-utero sounds.
  • If the baby typically poops just after falling asleep, use generous quantities of a diaper cream to prevent irritation.
  • Be prepared for your baby to be hungrier at night. Toward the end of the feeding, swaddle the baby so that he or she will fall asleep ready for bed.
  • Make sure the baby does not touch anything cool as you put him or her down to sleep.
Biological Clock in HumansEarly research into circadian rhythms suggested that most people preferred a day closer to 25 hours when isolated from external stimuli like daylight and timekeeping. However, this research was faulty because it fa…iled to shield the participants from artificial light. Although subjects were shielded from time cues (like clocks) and daylight, the researchers were not aware of the phase-delaying effects of indoor electric lights.[27] The subjects were allowed to turn on light when they were awake and to turn it off when they wanted to sleep. Electric light in the evening delayed their circadian phase. These results became well-known.[28]More recent research has shown that: adults have a built-in day, which averages about 24 hours; indoor lighting does affect circadian rhythms; and most people attain their best-quality sleep during their chronotype-determined sleep periods. A study by Czeisler et al. at Harvard found the range for normal, healthy adults of all ages to be quite narrow: 24 hours and 11 minutes ± 16 minutes. The “clock” resets itself daily to the 24-hour cycle of the Earth’s rotation.[

Light and the biological clockLight resets the biological clock in accordance with the phase response curve (PRC). Depending on the timing, light can advance or delay the circadian rhythm. Both the PRC and the required illuminance vary from… species to species and lower light levels are required to reset the clocks in nocturnal rodents than in humans.Lighting levels that affect the circadian rhythm in humans are higher than the levels usually used in artificial lighting in homes. According to some researchers[35] the illumination intensity that excites the circadian system has to reach up to 1000 lux striking the retina.

In addition to light intensity, wavelength (or colour) of light is a factor in the entrainment of the body clock. Melanopsin is most efficiently excited by light from the blue part of the spectrum (420–440 nm[36] according to some researchers while others have reported 470–485 nm). These blue wavelengths are present in virtually all light sources, therefore their elimination requires special lights or filters which appear amber.

It is thought that the direction of the light may have an effect on entraining the circadian rhythm;[35] light coming from above, resembling an image of a bright sky, has greater effect than light entering our eyes from below.

According to a 2010 study completed by the Lighting Research Center, daylight has a direct effect on circadian rhythms and, consequently, on performance and well-being. The research showed that students who experience disruption in lighting schemes in the morning consequently experience disruption in sleeping patterns. The change in sleeping patterns may lead to negatively impacted student performance and alertness. Removing circadian light in the morning delays the dim light melatonin onset by 6 minutes a day, for a total of 30 minutes for five days.
