My DD2 is cutting her penultimate tooth.
It has always been difficult.... but besides the crying and whining she's been having terribly bratty outbursts. 
I know she's in pain and it's not her normal but I have to draw a line! Today she turned her sister's soup bowl upside down, she keeps throwing stuff (more than usual). She wanted orange and it was a REALLY difficult one to peel. I managed to fight 3 segments out of it but she threw that at me and sais she wanted the one attached to the peel 
well... no! You can't!
What do you do?.... she went to the naughty chair like 5 times today...
