But why babies smile in their sleep? Is it a reflex or a genuine expression of happiness?
To answer these questions, we need to understand how babies sleep, how they develop their facial muscles and emotions, and what factors influence their smiling behavior. We will also share some tips and suggestions on how to stimulate your baby’s smile, both during sleep and awake.
By the end of this article, you will have a better understanding of why your baby smiles in their sleep, and how you can make them smile more often.
What is a newborn baby’s sleep pattern?
One of the factors that influences your baby’s smiling behavior is their sleep pattern. Newborns generally sleep 12 to 16 hours in a 24-hour period, but they do not know the difference between day and night. They usually sleep in short periods of 20 to 50 minutes, and wake up for feeding every few hours.
Newborns have two types of sleep: REM (rapid eye movement) sleep and non-REM sleep. REM sleep is the stage when babies dream and show eye movements and facial expressions. Non-REM sleep has four stages, from light to very deep sleep. Babies cycle through these stages several times during sleep, and may wake up as they pass from deep to light sleep.
Newborns spend up to half of their sleep time in REM sleep, which is much more than adults. This may be because REM sleep is important for brain development and learning. REM sleep is also the stage when babies are most likely to smile in their sleep.
Newborns enter REM sleep right after falling asleep, unlike adults who usually enter REM sleep after 90 minutes. This means that newborns have more opportunities to smile in their sleep, especially in the first half of the night. However, this also means that they are more easily disturbed by noises, lights, or movements, and may need your help to fall back asleep.
Why Babies Smile in Their Sleep?
Now that we know how babies sleep, let’s look at the possible reasons why they smile in their sleep. There are different theories and explanations for this phenomenon, and they may vary depending on the baby’s age and stage of development. Here are some of the most common ones:
Reflex:
One of the simplest and most widely accepted reasons why babies smile in their sleep is that it is a reflex. A reflex is an involuntary action that happens without conscious thought or control. Babies are born with many reflexes, such as sucking, grasping, and rooting, that help them survive and adapt to their environment.
Smiling may be one of these reflexes, that helps them develop their facial muscles and prepare for social interactions later on. Reflexive smiles usually appear in the first few weeks of life, and can be triggered by various stimuli, such as touch, sound, or light. They are not related to the baby’s emotions or feelings, and can occur during any stage of sleep.
Muscle development:
Another possible reason why babies smile in their sleep is that it is a sign of muscle development. As babies grow, they start to gain more control over their facial muscles and expressions. Smiling in their sleep may be a way of practicing and strengthening these muscles, as well as exploring different sensations and movements.
Muscle development smiles usually appear between 2 and 3 months of age, and are more frequent and varied than reflexive smiles. They are often accompanied by other facial expressions, such as frowning, grimacing, or pouting. They are more likely to occur during REM sleep, when the baby is dreaming and more active.
Dream imagery:
Another possible reason why babies smile in their sleep is that it is a response to dream imagery. Dreaming is a complex and mysterious process that involves the creation and interpretation of images, sounds, and emotions in the brain. Babies may start to dream as early as the third trimester of pregnancy, and their dreams may reflect their memories, experiences, and feelings.
Smiling in their sleep may indicate that babies are having pleasant or positive dreams, such as seeing their parents’ faces, hearing their voices, or feeling their touch. Dream imagery smiles usually appear between 4 and 6 months of age, and are more genuine and expressive than reflexive or muscle development smiles. They are also more likely to occur during REM sleep, when the baby is dreaming and more active.
Inner contentment:
Another possible reason why babies smile in their sleep is that it is a manifestation of inner contentment. Inner contentment is a state of being happy, satisfied, and at peace with oneself and one’s surroundings. Babies may experience inner contentment when they feel comfortable, safe, and loved. Smiling in their sleep may be a way of expressing and communicating this inner contentment to themselves and others.
Inner contentment smiles usually appear between 6 and 12 months of age, and are more consistent and intentional than reflexive, muscle development, or dream imagery smiles. They are also more likely to occur during non-REM sleep, when the baby is in a deep and restful sleep.
As you can see, there are different reasons why babies smile in their sleep, and they may change as the baby grows and develops. However, regardless of the reason, seeing your baby smile in their sleep is always a delightful and rewarding experience, and one that you should cherish and enjoy.
