Swallowing is difficult, so far the ques ive been following have been

1. Sip water

2. Put water to tip of tongue

3. Move tip of tongue a bit

4. Then sweep tongue starting from the back, aim for the throat 

5. Dont engage cheeks at all and push up till the swallow is engaged 

My reference for this has been this video about tongue sweep https://youtu.be/6_7MQWzjAL0

Is tongue sweep the same as mew swallow?

Is this correct or am i doing it wrong? I find it difficult to keep my mouth closed and head stable during the swallow and there's a lot of burping, should i just practise more? Do you use a mirror?

What about for solid food? 

Chew until its mush and proceed to swallow the same? Is there a certain way to chew correctly(,make sure i'm not using the buccitator muscles)? Should my mouth be open or closed while chewing?

Thanks
