How is your head and spinal alignment/balance? Are your muscles, organs, bones correctly organized? Or is there some tension anywhere?

If there is a downward pull because of tension and compensations + the force of gravity, it will very difficult to let the tongue be activated by the reflexes, which give her all that strength.

The tongue is connected to the hydoid bone, which is also connected to the mandible, so, for example, if your jaw is not free and is full of tension, the tongue wont be able to exert as much as force. Or, if you are pushing your belly out, the organs wont be able to support your diaphragm, pulling everything down, including the tongue (even though you could still push with it)..

When your muscles are chronically stretched because of tensions, they cant function properly. They wont contract and release as they should (which gives them proper tone). Specially involuntary actions like breathing, swallowing, peristalsis, etc. 

If your body is perfectly balanced, in it's form, structure and function, then I dont know what the problem may be. 

I try and practice good posture all the time. I keep a constant chin tuck and a straight back. I don't feel any peculiar tension. My jaw isn't tense and is barely open or barely touching. gut is in.

Hmm, I dont see the chin tuck necessarily as a sign of good balance (the same goes for the straight back). Its entirely possible and actually probable to have imbalances with a chin tuck. Not to say that you shouldnt do it at all. Rather, to make sure to balance your head/skull on the weightbearing part of your spine, so that when you do a mckenzie chin tuck, you do it without tension or distorting your heads movement. 

I also encourage you to increase your body awareness (with attention/mindfulness and help of your senses, like touch and kinesthesia/proprioception) to be able to listen to any feedback your body may be trying to give you.

Is your palate very narrow? What is your IMW?

I keep my head on top of my spine. IMW  is about 36

tbh im pretty convinced my bones are fused. I never get any movement sensations.

Hmm, its not the ideal starting point, but it could be a lot worse. 

So, if you dont have chronic stress at the moment, you sleep well, exercise, eat enough calories (maybe a little bit more than normal, as some people here have mentioned), you dont have hormonal imbalances, take important vitamins (including K2, D, etc), you have a suction hold/push swallow, you do myofunctional exercises, and you are 200% sure both tongue and body posture are correct (as krollic's thread suggests).. then Im not sure what the problem is.

Have you seen fotos of 8 months ago? As the change is not so fast, sometimes perception needs some time to catch up. 

Maybe you need help with  an expansion appliance and/or to contact a myofunctional therapist, as they measure how strong your muscles are and how your swallowing is.

Hey Op try something

say wing

when you mew are you making the same ng sound with your mouth naturally  or does your lower 3rd lower

If you don't feel any pressure sensations you shouldn't expect any results. It probably means you're doing something wrong.  Even if bones are fused they still change from force.

@auxiliary7, he did say he feels pressure in the palate region. 

@neural, could you please put your hand on your face fingers spread on forehead and cheekbones, palm on nose and place your whole tongue on your palate ( do a suction hold/push swallow, say wing as gubbb suggests, etc). Do you feel pressure on your hand?

Mike Mew mentions the pressure on the forehead somewhere.

I also agree that even if the bones were fused (which I don't think so) expansion has more to do with hormones from the pituitary gland (like growth hormone) excreted through the stimulation and rotation of the sphenoid bone, like this myofunctional therapist says in this interview:

EDIT: sorry, I meant to say to place the tongue like you always do, and see if your hand feels pressure. 

@gubbbbb I have my lower third plastered on the back of my palate. if i were to say wing the back position of my tongue would not change

@ayla31 to clarify, i can apply a pressure to my palate as hard as I want but I won't feel any of it in my skull, only in my tongue and skin in mouth being compressed..

If I do that hand/forehead exercise I can feel a slight pressure upon my fingertips from my forehead.      Is that my entire head being pushed forward or my skull expanding? i'm doubtful it's the latter. either way I can feel the slight movement.

can you guys elaborate on what rotates the sphenoid bone?

Best way to get results is with correct tongue posture. Best way to get correct tongue posture is to just strengthen the tongue. You won't have to think about pushing anymore if you just exercise the tongue. If you leave it up to your conscious actions then you are liable to make mistakes and have a negative effect, but if your tongue is strong it will naturally go up to the right position.

Same principle is applied in chiropractic treatment for posture.  Their main correction method is to just strengthen weak postural muscles. 

Neural, have you done myofunctional exercises (like tongue chewing, pushups, etc).

They not only build tongue strength, but also muscle memory.

Do you also chew gum?

I agree with bigbrain, if you havent already, try tongue chewing and pushing harder (as an exercise) every day to see what happens. 

And, like I said before, if your income allows it, its a good idea to have a consultation with a Myofunctional therapist, so that they measure your muscles strength and see also how your swallowing function is.

Rotation of the sphenoid happens when the back third of the tongue is on the roof of the mouth/soft palate.

Its good that you feel the movement on the forehead (I suppose it would've been good to feel something on the rest as well, but Mike did say on the forehead, so..). Its not your skull expanding, is just pressure (that in the long run affects bone shape). But how much pressure there is depends of course on how strong the tongue muscles are, among other things.

yeah i do all the tongue/jaw chewing stuff with tough gum. pretty sure I have powerful tongue and jaw muscles

I suppose you also measured your Mew indicator line and saw no changes either.

In that case I dont know what is wrong, sorry. I have read about some people who saw more results after a year or two of doing mewing, but not so much at the beginning. At least you feel pressure where you are supposed to. 

On another note, there are many people here that are experimenting with hard mewing and have good results (but there are other people who claim to have pushed and pushed without results, so... I dont know). Maybe you want to try that? 

I kind of doubt that you have strong tongue muscles. I did them for 1-2 hours per day for a week and the hard push posture had already become automatic.

SORRY I'm only commenting here because I don't know how to post on this forum.I wanted to share some information I got on youtube that will tell on how to measure forward growth here is the link:  https://youtu.be/ATxzGV67mmU

@bigbrain I reckon I could beat you in a tongue wrestling competition  😉 

I usually do about 30-60 minutes of high intensity chewing. More than enough to build up tongue strength. Could probably do it for a lot less than that tbh and still have a strong tongue

@neural Prove it. French kiss me ;P

._.

big brain honestly thats great advice ive been mewing concsiously to the point where i think its not helping me anymore i dont swallow naturally every swallow is concious im going to try to just strengthen the muscle.

@darkindigo

I don't believe the midpalatal suture fuses at puberty.  All the circummaxillary sutures never fuse till the 7th to 8th decade, they just become more interdigitated and therefore harder to modify with age.  The circummaxillary sutures probably served a "cushion" function in our ancestors, to help absorb the persistent and powerful pounding of the maxilla by the mandible during chewing and biting.
