Babies are one of life’s greatest mysteries; their tiny, precious smiles are a source of joy and wonder for parents, family, and friends. The delight that a newborn’s smile can bring is hard to describe. Even more mysterious is the fact that babies often smile in their sleep. Have you ever wondered why newborns smile while they are sleeping? Scientists have been studying this phenomenon for years, and while the exact cause remains unknown, some theories suggest that a baby’s smile is a physical response to pleasant dreams or a way of expressing joy and contentment. Whatever the reason, one thing is certain: a newborn’s smile is a beautiful and heart-warming sight.

What is a newborn smile?

Newborn babies usually begin smiling in their sleep between the ages of two and three weeks. At this point, their brains are fully formed and they can produce and respond to stimuli. In addition, they have enough energy to make eye contact, turn their heads toward sounds, and smile while they are sleeping. Although some babies tend to smile more than others, all newborns can smile. A newborn smile can appear when a baby is sleeping on their back, lying on their side, or being held in a parent’s arms. It is important to note that true newborn smiles are accompanied by squinted eyes, slow blinks, and a soft gurgling or cooing sound. Newborns often smile when they are dreaming, but it is not possible to know what they are dreaming about.

Theories behind the reasons why babies smile in their sleep

a. Physical response to pleasant dreams – Some experts believe that newborns smile in their sleep because they are dreaming about pleasant experiences, such as being in the womb or breastfeeding. When babies dream, their facial muscles are activated. This may cause them to open their mouths and create a smile-like facial expression even while they are sleeping. Similarly, a newborn’s smile could be a physical response to the feeling of being cradled and held.

b. Expression of joy and contentment – Another theory suggests that a newborn’s smile is a physical expression of joy and contentment. When babies are sleeping, they may be dreaming about pleasant experiences, which causes them to smile, even if they don’t know they are smiling. Some experts believe that this explanation is more likely because a newborn’s smile is accompanied by other positive physical reactions, such as slow blinks and cooing sounds.

The mystery of the newborn smile

The reason behind a newborn’s smile is a mystery. What we do know is that it is a beautiful and heart-warming sight. When a baby smiles in their sleep, it can help them to stay calm and restful. When babies are relaxed, their brains release a hormone that is associated with feelings of calmness and comfort. The same hormone is released when a baby is held in their parent’s arms. This may explain why babies often smile when they are being held. When newborns smile in their sleep, it is also important to remember that they cannot control the muscles in their faces. So, if your baby has a smile on their face, there is no need to worry. Simply enjoy the sight and be thankful for your little one’s joy and contentment.
