Like adults, children have dreams when they are in REM sleep. This occurs 4-5 times each night, and while most dreams aren’t remembered, some are frightening enough to wake the child and make them summon their parents. Nightmares usually begin when a child is about three years old, they are most common between the ages of three and eight (when their fantasy life is more active) and they are most likely to occur later in the night. Unlike night terrors, your child will be wide awake and responsive after the nightmare and she may be able to recall the details of the nightmare the next morning.

When will my baby start sleeping through the night?
Night Waking: or, Will I Ever Get A Good Nights Sleep Again?
The answer is no. Once you become a mother, you will never, ever sleep the way you did before you had your baby. Even when he starts sleeping through the night, which will happen eventually (I promise), you will always have your mom radar on and will be listening for a cry in the night. Even if he is a teenager out on a date, you will lie in bed waiting for his car to pull in the driveway before you can fall asleep. When he is middle aged and balding, you will still worry about whether 
he is taking care of himself the way he should.The question When will my baby start sleeping through the night? is one that I dread the most. Like most health professionals, I like questions that have easy answers, and this one doesnt. I do have opinions about how to handle sleep problems, based on my experience with nursing six children, and over twenty years of working with new mothers. What I dont have is a quick fix, or a magic solution for you that will make your baby sleep through the night.
Experts cant even agree on what sleeping through the night means. Some define a five- hour stretch as sleeping all night, others define it as an eight to twelve hour stretch. Sleep problems are a hot topic. There are dozens of books and hundreds of magazine articles on how to get your baby to sleep longer. In our culture, a good baby is defined as one who sleeps a lot and demands as little attention as possible. If you define sleep problems the way many experts do, then almost all babies have some sort of sleep problem.
Overview, Waking, Non-REM, REM, Sleep Cycle, Factors, Age
Since the early 20th century, human sleep has been described as a succession of five recurring stages: four non-REM stages and the REM stage. A sixth stage, waking, is often included. Waking, in this context, is actually the phase during which a person falls asleep. Rapid eye movement (REM) sleep is marked by extensive physiological changes, such as accelerated respiration, increased brain activity, eye movement, and muscle relaxation. People dream during REM sleep, perhaps as a result of excited brain activity and the paralysis of major voluntary muscles.
Dr. Michael J. Breus: Oh Canada, Get Some Sleep!
A recent study I read showed some interesting aspects about the sleep of our friends to the north, and they seem to be as bad as ours here in the US! The study recently published in the journal Sleep explained the economic cost associated with sleep disorders in Canada. Here are the bullets (all in Canadian $):
- total annual cost of insomnia (direct and indirect) in the province of Quebec was estimated at $6.6 billion
- prescription medications ($16.5 million)
- over the-counter products ($1.8 million)
- alcohol used as a sleep aid ($339.8 million)
- The total estimated annual cost of alcohol used for promoting sleep was $51.1 million spent by people with insomnia syndrome, $211.2 million by those with symptoms of insomnia and $77.5 million by good sleepers.
What everyone seems to be making a big deal about is the alcohol consumption number. My question is WHY?
Sleep researchers for YEARS have known that the #1 sleep aid in the world is alcohol. If you go back to the 1998 Sleep In America Poll, you find that 10% of all Americans had used alcohol in the past year to “help” with sleep. Another study collected in the Detroit area showed that 13% of those polled used alcohol as a sleep aid.
Self Soothing To Help Baby Sleep Through The Night
Self Soothing to Help Baby Sleep Through The Night Self soothing is the key to have baby sleep through the night. But what if putting baby down awake just doesn’t work (and it often doesn’t!)? You may find your baby crying unless you rock or nurse her to sleep. How to get rid of this habit?
Because no one (babies and adults) ever really sleeps through. Our sleep comes in cycles: we go through the different stages of sleep several times a night. In between cycles, there is a moment where we are as good as awake. The skill go settle ourselves helps us go straight back to sleep without waking up completely.
Babies who cannot self soothe yet will wake up completely at that moment, need your attention and possibly cry.

What is Sleep and the Effects of Sleep Deprivation Tina Chen
Sleep is one of the things that most students can say they do not get enough of. It is a time for us to rest and for a few blissful hours hopefully forget about the stress and worries of school and life. Unfortunately, due to too much work or too much studying to do, often enough, we do not get the amount we need each night to be fully rested the next day. But we have learned to cope with the sleep deprivation by drinking coffee in the morning to wake us up. Even though we are awake, how well can we function throughout the day when we have only had less than five hours of sleep? How much does our behavior change without enough sleep?
Before we get to what the effects of sleep deprivation are, let us first look at what sleep is. Sleep is controlled by neurotransmitters, which act on different neurons in the brain. Some of these neurotransmitters produced, such as serotonin and norephinephrine keep the brain active while we are awake. Researchers think that adenosine builds up in our blood while we are awake and the gradual breakdown of it causes drowsiness. There are five stages of sleep: stage 1, 2, 3, 4, and REM or rapid eye movement sleep. During stage 1-4 of sleep, our brain waves become slower and slower until we switch to REM sleep. At that point, our breathing is more rapid and irregular and our eyes move rapidly under our eyelids. (1).
The Stages of Sleep
There are five phases of sleep: stages 1, 2, 3, 4 and REM (rapid eye movement). Usually when you are sleeping, you begin at stage 1 and go through each stage until reaching REM sleep, and then you begin the cycle again. Each complete sleep cycle takes from 90 to 110 minutes. Your brain acts differently in each stage of sleep. In some of the stages, your body may make movements, but in others your arms and legs will be immobile. Having good sleep habits will make sure you get each type of sleep that you need.

Stage 1 Stage 1 sleep is light sleep. You experience a drifting in and out of sleep. You can be easily woken up. Your eye movement and body movements slow down. You may experience sudden jerky movement of your legs or other muscles. These are known as hypnic myoclonia or myoclonic jerks. These “sleep starts” can give a sensation of falling. They are caused by the motor areas of the brain being spontaneously stimulated. Stage 2 Around 50 percent of your time sleeping is spent in stage 2 sleep. During this stage, eye movement stops and your brain waves (a measure of the activity level of the brain) become slower. There will also be brief bursts of rapid brain activity called sleep spindles. Stage 3 Stage 3 is the first stage of deep sleep. The brain waves are a combination of slow waves, known as delta waves, combined with faster waves. During stage 3 sleep it can be very difficult to wake someone up. If you are woken up during this stage, you may feel groggy and disoriented for several minutes. Stage 4 Stage 4 sleep is the second stage of deep sleep. In this stage the brain is making the slow delta waves almost exclusively. In this stage it is also very difficult to wake someone up. Both stages of deep sleep are important for feeling refreshed in the morning. If these stages are too short, sleep will not feel satisfying. REM Sleep – Rapid Eye Movement REM sleep is the sleep stage in which dreaming occurs. When you enter into REM sleep, your breathing becomes fast, irregular and shallow. Your eyes will move rapidly and your muscles become immobile. Heart rate and blood pressure increase. Men may develop erections. About 20 percent of sleep is REM sleep for adults.

When Counting Sheep Fails: The Latest Sleep Medications
Insomnia has been around as long as sleep has. Some even believe that William Shakespeare was an insomniac, writing as vividly as he did about sleeplessness, tossing and turning, and sleepwalking in plays like Hamlet and Macbeth. Today, old Will has millions of fellow sufferers.
- The 2007 Sleep in America Survey from the National Sleep Foundation found that 67% of women say they frequently experience a sleep problem.
- The 2005 Sleep in America poll found that 35% of adults experience insomnia every night. Â
One option today’s insomniacs have that Shakespeare didn’t, of course, is the sleeping pill. Over the last 10 to 15 years, the market has been inundated with new and improved sleep medications — ones that don’t come with the same degree of hangovers, side effects, and risk of dependency that previous sleep drugs did.
Healthy Sleep in Children

Good, Sound Sleep for Your Child Essentials of Healthy Sleep continued…
Quality of sleep: Quality sleep is uninterrupted sleep that allows your child to move through all the different and necessary stages of sleep. The quality of sleep is as important as the quantity, playing its essential role in nervous system development.
Naps: Naps play a large role in the healthy sleep of children. They help optimize your child’s alertness and have an impact on her learning and development. Naps are also quite different from night sleep. Not only are they not the same kind of sleep, naps at different times of the day serve different functions. That is one reason why the timing of naps is important, and why they need to occur in sync with your child’s natural biological rhythms.
REM Sleep Behavior Disorder Causes
REM Sleep Behavior Disorder REM Sleep Disorder Overview
Normal sleep has 2 distinct states: non-rapid eye movement (NREM) and rapid eye movement (REM) sleep (see Sleep: Understanding the Basics for details of various stages of sleep). NREM sleep is divided into 4 stages. During REM sleep, rapid eye movements occur, breathing becomes irregular, blood pressure rises, and there is loss of muscle tone (paralysis). However, the brain is highly active, and the electrical activity recorded in the brain by EEG during REM sleep is similar to that recorded during wakefulness. REM sleep is usually associated with dreaming. REM sleep accounts for 20-25% of the sleep period.
