At the beginning of a baby's life, there is little consciousness and they live aimlessly every day, only instinctive reactions. However, it won't be long before babies have their own consciousness, and their facial expressions will also be very rich, such as silly laughter, wrinkled nose, and sticking out their tongue. So, why do babies like to stick out their tongues?
Babies under 1 year old are very interested in lip movements. Due to the rapid development of the oral nerve in infants, which develops earlier than other parts of the body, children at this time are more inclined to seek oral satisfaction, especially after being breastfed. The baby's sense of satisfaction is strong, so they love to stick out their tongue.
After two months of birth, the salivary glands in the baby's mouth begin to secrete saliva, and the child will lick with their tongue. At this point, parents will see the baby sticking out their tongue. If a child's lingual frenulum is too short, they will not be able to extend their tongue out of their lips properly, which can have a significant impact on their breastfeeding and speech learning. If a baby frequently sticks out their tongue, it indicates that their tongue is well-developed.
A newborn baby is always full of curiosity and will explore with their mouth and tongue before learning how to use their hands. And sticking out the tongue is a baby's exploratory movement, which can promote their growth and development.
