Well, using ultrasound, researchers were able to exactly see what happens during breastfeeding inside an infant mouth.
The key learning point discovered from the ultrasound images is that milk expression is due to a vacuum created within the infant mouth that occurs from the up and down movement of the tongue.
Why would an ENT be even writing about this topic???
It is because of the importance of the tongue's vertical motion that may explain why infants with tongue tie or posterior tongue tie have breastfeeding difficulties. In this situation, the tongue is tethered to the floor of the mouth preventing the tongue from moving upward and by surgically correcting, breastfeeding difficulties can be solved easily.
Watch video on breastfeeding problems due to infant factors.
