Okay my little sister keep stealing from home. At first it was candies, and cookies my mom bought for treats; she would take the hole box and eat it all. My mom wouldn't get mad at her she would sit down and talk to her trying to find out why she was doing this. Eventually it got worst, she stole money from my mom and step dad. And its not like my mother doesn't buy my little sister things she wants. My mom does what she can to give what everyone wants. Now my sister is stealing from me. My money, my make up and iPod. And she's only getting worst. MY mother is at the point where she doesn't know what to do anymore. I want to be able to help my little sister, before it's to late... Please help... Thanks

You have to help her overcome this behaviour right now or else it will be a bitter future for her. Never accuse her and be harsh to her. Let her know that you still love her no matter what and take her to a good physcologist ASAP.

I had a bit of a theft habit when I was young.
Best thing you can do as the older sister is NOTHING.

Talk to your parents. And if it gets any worse, your parents should be calling the police.

I was stealing little things at home then slowly started progressing to stealing from frinds at school. When I came home with a bike that wasn't mine, my mom called the cops. And they certainly made me see the error of my ways.

Chocodrip, I disagree, there MUST be a punishment here. Not acceptance.
But the punishment is not to come from the sister. The older sister needs to talk to her parents

Catkitten, I am sorry you disagree with me. But you are her sister. Not her mother. You trying to handle the situation will only cause her to resent you. Your mother needs to have your sister see a psychiatrist/psychologist. And get the kleptomania under control. It is an addiction and should be treated as such.
