I'm not sure what is triggering your emotions, but it is inappropriate.

What is more appropriate is to be prepared to say "No" to this child.

If he is not doing what you want him to do, get in the habit of offering him TWO choices (objects or things to do).

It is also important that you reinforce behaviour you do deserve (tho be careful the reward isn't food).

Finally, ensure you are taking the time to spend some quality time and attention with the child one on one. Reading is the best thing you can do. He is old enough to colour with you, to make a craft with you, or crawl around on the floor with you playing with toys.

I just want to say IN MY OPINION the worse thing you can do is give the child something like a phone or tablet to play with. You are just reinforcing the child's expectation for immediate gratification and attention while at the same time reinforcing a failure to communicate.
