I know it's tough but this is the time that they test us if we will give in if they keep on crying or keep on shouting...etc.

As tiring as it is...keep strong on your word, because eventually he will get it.

I have 2 boys that both went thru the same thing like your son, and I thought I was going to just lose it, but when my older son started reprimanding my toddler the same way I did to him when he was a toddler then I knew that he was listening :-)
