Understanding Oral Function: 5 Oral Reflexes That Affect Feeding
If you’ve ever been told your baby’s latch “looks fine,” but feeding still feels difficult, frustrating, shallow, exhausting, or painful…you’re not imagining things.
A baby can technically latch and still struggle to use the muscles inside their mouth effectively during feeding. And sometimes the missing piece is not just whether a baby can suck, but how well their tongue, jaw, cheeks, and reflexes are working together to create a vacuum and transfer milk comfortably.
In this video, I walk you through five reflexes you can observe at home that give important clues about oral function and tongue movement during feeding.
These reflexes are part of the communication between your baby’s brain and the muscles inside their mouth. They help us understand how effectively your baby can organize movement for feeding, transfer milk, and maintain suction.
Inside this video, I'll help you learn:
- how to assess your baby’s gaping reflex and why it matters for a deeper latch
- what the suck reflex can tell you about tongue coordination and feeding organization
- how to observe tongue extension and lateralization reflexes to better understand tongue mobility
- what rhythmic ...

- why feeding challenges are often about mechanics, vacuum, and muscle coordination — not just milk supply
Understanding how your baby’s mouth moves during feeding can completely change how you understand latch, transfer, and breastfeeding struggles.
