she's 6 almost 7, i dont really know is it me being a bad mother or what. she has never lied, and once she started going to school and with her friends she started lying. i would ask her something i knew that she did do, and she would lie about it, until i yell at her. now just today, she took some of my money, without even asking, she really cant tell what $1 are like and $20, so she took five of my 20 dollar bills to school, and when i came home i found one left in her pocket. before her dad asked her and she said no, so i found it and got really mad, and we asked her to go to her friends house and get the money back since she gave it to her friends. i don't know what to do, i am so mad, and my husbands all like, well don't put your stuff there. what can i do to make her a better person?
