A lot shorter in adults than in babies (only 2 to 4 percent of sleep time)

Q

Non-REM phase 2 differences between baby and adult

A

An adult spends 45 to 55 percent of the time in this phase, a baby, much much less.
The older a child gets, the more time is spent in this phase and less in the REM phase.

A

Deep sleep
Whole body relaxes
Sleep talking and sleepwalking are possible at the start of this phase.
Possible nightmares and night terrors at the end of this phase.

Q

When’s the best time to try and put baby down or leave baby alone?

A
  • During non-rem phase 3 when baby is in a deep sleep and unlikely to wake from the transition.
  • It’s also possible during non-rem phase 2.
  • try picking baby’s arm up while they are in this phase. if the arm falls limply when you let go, it is safe to put baby down. if the arm falls but still under baby’s control, wait longer.

Q

What are babies’ sleep characteristics during early pregnancy?

A
  • baby does not contribute to a sleep-wake rhythm or day-night rhythms.
  • The day-night rhythms they display are caused by substances such as melatonin, that enter their body through the mother’s blood via the umbilical cord.

Q

What are baby’s sleep characteristics when they are born?

A
  • After cutting the umbilical cord there is no longer a melatonin supply through mother’s blood. There is no reserve.
  • They do not display day-night rhythms yet.
  • When it comes to producing sleep hormones, light and dark do not yet have an affect.
  • short sleeps, long sleeps, in daytime, at night. Your baby sleeps when they feel like it.

16
Q

What happens during the first week after baby is born that affects sleep?

A
  • The day-night rhythm of baby’s body temperature starts.
  • it is not noticeable as a day-night rhythm yet, but it has started in their brain.
  • To obtain a good sleep-wake rhythm, your baby first needs the day-night rhythm of the body temperature.
17
Q

What are baby’s sleep characteristics at 6 weeks old?

A
  • Your baby now has the foundation of a waking rhythm but not of a sleep rhythm yet.
  • You will notice that the times of being really awake and the times of being tired cannot be so clearly distinguished anymore.
  • At first your baby’s wakeful and sleepy times were spread out in disarray over the day and night, those short chaotic moments now seem to get closer together.
18
Q

What happens in the 2nd month of life that affects sleep?

A
  • Baby begins to develop the very first precursors of a sleep-wake rhythm.
  • You will not notice it immediately but, biologically, the night rhythm has started in the developmental process.
19
Q

What is baby’s sleep like at 3 months?

A

The time your baby sleeps during the day decreases and the time they sleep at night increases.

20
Q

What are baby’s sleep characteristics from 3 months to 6 months?

A
  • A pattern increasingly develops in the production of melatonin at night.
  • From now on, a difference in cortisol levels between night and day can also be measured.
  • From 15 weeks onward, you will notice that your baby has a clear sleep pattern over 24hours.
  • Baby has set sleeping hours during the day and night.
21
Q

What are some things that can disrupt baby’s normal sleep patterns once they are developed?

A
  • health and safety issues
  • going through a developmental milestone (a leap).
  • traveling
22
Q

Why shouldn’t we try to change a newborn’s sleep to look like an adults?

A
  • Their sleep patterns are a biological process that aids in their survival.
  • a newborn cannot sleep too long without eating and exercising it’s lungs.
23
Q

How long is a newborn’s sleep cycle?

A

approximately 40mins

24
Q

How long is an adult’s sleep cycle?

A

approximately 120mins

25
Q

At what age does a child’s sleep cycle start looking like an adult’s?

A

When they are school aged, their sleep cycles are 90-100mins.

26
Q

Survival reasons baby wakes during the night?

A
  • Their stomachs are very small and milk digests rather quickly. They do not have a ration stored.
  • It is important for your baby to wake up if something is causing them discomfort or if something could harm their body.
  • Something could obstruct their breathing (like mucus in their nose).
  • Baby instinctively knows it depends completely on you for survival. It is primeval that they desire to be close to you when they sleep.
  • They can’t control their body temperature.
27
Q

How does going through a leap affect baby’s sleep?

A
  • Most babies will experience sleep disturbances while going through a leap.
  • Sleep disturbance is more prevalent during the leap but it is also there when the difficult phase of the leap is over, albeit, to a lesser extent.
28
Q

How does going through the first 3 leaps affect baby’s sleep?

A
  • Baby does not yet have a day-night rhythm so it will be difficult to determine that the sleep rhythm was disturbed by a leap.
  • Daytime naps will be easier to notice a difference in.
  • Baby will sleep more lightly, for shorter periods of time, or even longer than normal.
  • Baby may be especially influenced by stimuli and find it hard to sleep. Help baby out by giving them moments to rest without distractions.
29
Q

During which leaps is sleep regression likely, and why?

A
  • leaps 4, 6 and 10.
  • These leaps correlate with the body learning new skills not just the mind. So baby is not only dealing with the mental aspect of growing but also the physical consequences of practicing new skills.
30
Q

What is often the first sign of a leap beginning, and at what point is it noticeable?

A
  • Poor/worse sleep habits are often the first sign.

- observable from leap 4 and on, at which point baby has a stable sleep rhythm.

31
Q

At what age do night terrors usually occur?

A

Night terrors usually occur around age 3 but can occur in children as young as 2.

32
Q

What is a night terror like? Do children remember them?

A
  • A night terror is a real panic attack during sleep.
  • You can’t get through to them and whatever you do only seems to make it worse.
  • They will not remember it the next day.
33
Q

At what age do nightmares occur? Do children remember them?

A

They can occur in babies as young as 4 months.

- children can remember them but depending on ability, may not be able to communicate them.

34
Q

When are nightmares more likely?

A
  • Nightmares peak in stressful times and so they often happen during leaps but
  • they can occur during periods of no stress.
  • Babies will have more nightmares during the period of separation anxiety (which peaks between 8 and 10 months)
35
Q

How can we help a child who is having a nightmare?

A
  • The majority of physicians say not to wake a child during a nightmare.
  • Being there with them, talking to them, putting a hand on them, soothing them back to a peaceful phase is helpful.
  • Use your intuition though (if you think its so bad and need to wake them; do so).
36
Q

What percentage of babies have had a nightmare by the 6th leap? 10th leap?

A
  • 40%

- More than half
