En En seems understand and behaved better than before after she realized she can't use crying to get what she wants. Maybe it's true everyone in the family must co-operate and firm in teaching her what she done is acceptable and vice versa.
Right now whenever she did something wrong or cry without any reasons we will tell her that we are going to whack her again and she said: "Ah Mah ta-ta (beat buttock)!"
She only allows Ah Mah to whack her... *roll eyes*
Another method to stop her from crying is by telling her there is a mozzie or a housefly is flying into her big mouth and this works! :)
