Toddlers between the ages of one and a half and three often have temper tantrums as a means of giving vent to frustration when they do not get what they want.
This is quite normal because your child will not have sufficient judgment to control her strength of will or the language to express herself clearly, but as her knowledge and experience of the world broaden, the occasions when her will is pitched directly against yours become less frequent.
A tantrum may be brought on by such feelings as frustration, anger, jealousy, and dislike. Anger is brought on by not getting her own way; frustration by her not being sufficiently strong or well coordinated to do what she wants. It will usually involve your child throwing herself on the floor, kicking and screaming.
The best thing you can do is to stay calm, since any attention on your part will only prolong the attack. If she has one in public, take her away from too much attention, without fuss.
At home, an effective technique is simply to leave the room. Explain to your child that, while you still love her, you have to leave the room because you are getting angry.
Never confine her in another room because this denies her the option of coming back and saying she’s sorry.
