terrible twos

Talk about a temper. Everyday Nicholas is testing everybody to see how far he can go and on most days, he can get away with anything as long as grandma's around.
He'll sweep things off the table, throw his toys around, scatter his books on the floor and even hit his grandma. These are just a few examples of his misbehaviour. Of course most of the time these things happen when I'm not around.
He knows that I'll discipline him if he does any of the above.
