Sure, here is the translation of the text in both English and Russian: English: Incorrect swallowing

The position of the tongue plays a major role in the formation of the food bolus and the development of incorrect swallowing. For children under 2 years old, the innate sucking reflex is still present, so infantile swallowing, which involves the participation of the lip muscles in the swallowing reflex, is considered normal. In this case, the tongue is positioned between the upper and lower teeth. However, if infantile swallowing continues beyond 2 years of age, it is considered a disorder and is one of the primary causes of orthodontic and myofunctional anomalies.
