some unfair things
I have a 4 years old son,
He is a very bright boy.
as he gets older he becomes more acting up
as you know,most of children like playing games on ipad,and watch cortoon and so on,but it will strain the eyes if spend too much time on this.
sometimes,he makes the room at sixes and sevens,and has the toys everywhere...
so i have to teach him don't do this,don't do that and tell him to keep out of mischief!
I usually say:If you're still naughty I'll smack your Bottom .
I don't remember how many times i had said
One day,i said the same words to my 4 years old son when he was acting up
my son shouted at me:"It's unfair!"
at that time,I'm at a loss for words!
