The tongue-thrust reflex, also known as the extrusion reflex, prevents infants from ingesting solid foods by pushing the solid out of the mouth with the tongue. This reflex typically diminishes around 4 to 6 months of age, which coincides with the developmental period when infants are more capable of starting to eat solid foods.
