So i only put the tip of my tongue behind the front and a bit of mid tongue on the maxila floor and i do all that firmly like no extra pressure do you think its the correct way or should i plaster all the tongue on the upper floor? Do you think either way mentioned above can be considered correct?
It should really be your entire tongue for best results. The easiest way is to practice the mew push swallowing using the cheesy swallow and very very cheesy swallow methods. Both are important even though the second one is weird. A good swallow will lead to good tongue posture. A bonus technique is to say gagagaga kakakaka over and over again, paying special attention to the muscle you are using, to strengthen the back part of your tongue.
