Why Do Babies Make an "O" Shape with Their Mouths?

As a parent or a curious person, you might often wonder why babies make an “O” shape with their mouths. Concerns are raised by this unusual behavior. Experts in child psychology, physiology, and communication have provided a plethora of explanations as we explore the intriguing field of infant development.

  • We reckon that the "O" form is an instinctual sucking reaction for most babies. In order to eat, newborns can latch onto their mother's breast or a bottle owing to this mechanism. The mouth's "O" shape assists in forming a good seal, making it easier to consume milk or food.
  • The “O” formation by babies’ mouths is also linked to language development in the early stages which encourages better development of speech, later on.
  • Toddlers are believed to be extremely inquisitive in nature, always looking for ways to learn something new. The shape of “O” being formed by little babies’ mouths are often said to be an expression of surprise or fascination. Thus, the next time you come across your little one doing that gesture, there’s a high possibility that they are amused by something in their surroundings and are absorbing more visual information.
  • Different emotions can be connected to the "O" mouth shape. As babies respond to things that grab their attention, it might be an indication of astonishment amazement, or joy. Babies often express their emotional response to those around them by making an "O" shape.
  • We reckon that babies are highly observational in nature and tend to learn from those around them. They have been observed to frequently imitate their caretakers' facial expressions and body language. In various situations, they might attempt to imitate the "O" shape made by others if they perceive it as a way to communicate.
  • Another theory proposed by experts is that toddlers' oral motor abilities are developed significantly through their mouth exhibiting the "O" shape. In order to prepare the mouth, lips, and tongue for a variety of activities like eating, talking, and subsequently chewing solid foods, these muscles are strengthened.

As a parent, it is important for you to note that the theories mentioned aren’t mutually exclusive and several factors can simultaneously be held responsible for your little one making an “O” shape with their mouth.
