After watching the technique I just posted, these images can really help you understand what your fingers are actually working on.
Under the tongue isn’t just a single piece of tissue (like a frenulum) — it’s a layered network of muscles and fascia that all work together.
Key muscles you’re influencing:
- MylohyoidForms the floor of the mouth and provides a supportive “sling” for the tongue
- GeniohyoidHelps lift and stabilise the tongue and plays a role in swallowing
- Digastric musclesSupport jaw movement and coordinate with tongue function
- Genioglossus & HyoglossusThese are deeper tongue muscles that control tongue movement and positioning
Why this matters:
When these muscle layers are tight or restricted, it can impact:
- Tongue mobility
- Feeding and latch
- Swallowing patterns
- Oral development
- Even breathing patterns over time
Bringing it back to the technique:
When you’re gently working under the tongue:
- You’re not just “stretching” tissue
- You’re helping these muscle layers relax and coordinate better
- You’re improving how the tongue can move, lift, and function
This is why you may feel those pea-sized tight spots — they’re often small areas of tension within this system.
The takeaway:
This work is gentle… but powerful.
Understanding the anatomy helps you:
- Be more confident
- Be more precise
- And be more consistent with your child’s care
