It's not a big deal :) I had the same thing starting out and my molars expanded and I now have plenty of space.

Similar thing here. At the beginning, I was not able to put my tongue on my palate, except for the very tip. Through a lot of effort I managed to shift my second molars (last teeth, since my third molars are gone), just far enough to put my tongue between them. By that point, I was able to have my posterior third and tip up against the palate, with the middle part hanging down a little. Once I figured out tongue suction, I progressively managed to get more and more of the mid section up, and have literally just today, for the first time, figured out how to get my entire tongue suctioned to my palate. Some of this is due to teeth tipping, but it's very likely that a little bit of expansion has occurred as well, because I have noticed minor aesthetic changes.

@elwynn

How do you make sure the mid section is touching the palate. That seems to be my problem too. I swallow and hold that position for the posterior third, but not too sure about the middle section. Also, is it normal that when i breathe through my nose it makes lots of snorting/ snoring like noises. Lastly, how important are posture and chewing  in your opinion?

Try activating different regions of the tongue separately. Touch your palate with just the tip of your tongue first, and take note of how that feels; then, touch your palate with just the back of your tongue, and take note of how that feels; finally, touch your palate with just the mid-section of your tongue, letting the tip and posterior hang, and take note of how that feels. Afterwards, when you suction the entire tongue to cover your hard and soft palates, you should hopefully be able to distinguish whether the mid-section is making contact.

Also, is it normal that when i breathe through my nose it makes lots of snorting/ snoring like noises.

It's definitely normal for someone starting out, but it's not ideal. Snoring noises can be produced when the back of the tongue is not securely suctioned to the soft palate and vibrates in response to the air passing through the throat; and / or when the tongue obstructs the airway. What you're experiencing is most likely caused by a lacking oral posture, insufficient space, or both. I struggled with the same thing about a year ago, but it gradually went away. The turning point was gaining better control over my posterior third, and learning how to raise my hyoid. These abilities may come with time, as the tongue and other muscles build their strength. If the problem is caused by insufficient space, then there's a possibility that it may also resolve with time, as your soft tissue begins to adapt to the new oral posture. Those types changes I think tend to occur much sooner than any skeletal changes, but they do make a difference. Assuming that breathing while mewing is not too uncomfortable for you, I would give it time to see whether it improves. If it doesn't, I'd try a different approach.

@elwynn

I have this exact same snoring noise. I feel as if I have to stop lifting my hyoid to breathe every time.

Although since the last few months its been a lot easier to keep the posture properly.

@oatmeal

Could it be that you're raising your hyoid too much? I raise it gently, and I'm so used to it that it's nearly effortless. I don't raise my hyoid as high as it can go, because it will then block off my airway. I think it's about getting all the forces acting in and around the mouth in balance.
