Dear Friend:
First and foremost **HUGS**
I am a step mom to 11 and 13 year old girls, and I have 2 myself, ages 7 and 9. There are really up days, and there are some days that I wonder how in the world I am going to get through it. Sure, when we married our husbands we knew they had children. That being said, there are bumps and bruises along the way...much like marriage
I respect that you kept the reasons of her punishment quiet... What it shows us is that you have complete respect for your stepdaughter and that is something to be respected and admired.
So - here is my insight. My 13 year old step daughter is amazing- she is a joy, amazing and easy. My 11 year old step daughter is a sweet child also- but she is the one that is the quickest to rebel, talk back, and disobey rules. We have stepped up the punishments with the various "offenses" for a lack of better terms. Grounding, Cheerleading taken away, and finally, her room cleared out of any personal items (a suggestion that I was appalled by at first, but actually really worked).
In each punishment we also talked...and talked...and then talked a little more... And we learned something amazing...
My 11 year old step daughter felt like she was betraying her mom if she had fun with us. She felt she was honoring her mom by disliking me. In her mom she was defending her mom, in the way she knew how... It changed our perspective, and allowed us to address a very real emotion in her head. Does it mean everything is peaches and roses now...no
... But it gave us perspective to her mind...
Long post, all to say... it is important to have rules and consequenses in your house that you and your husband agree on, and are explained to her. And it is also important that she knows that she does not have to choose between her mom and her dad. We say OFTEN in our house... We are all on the same team!
Good luck- she is lucky to have you!
