E.P.
I raised 4 kids and if this is the worst problem that you have to worry about, then stop and count your blessings!! I have 3 pieces of advice: 2 are very worthy, one is a bit silly, but might work.
1) Read the book, "How to Talk So Kids Will Listen, and Listen So Kids Will Talk." I read it multiple times during my first 10 years as a parent. Eventually, I loaned it out. Had to go buy another copy. Easy reading, and it works!!!
2) "Love and Logic" parenting classes offered by many school districts. I actually went to a live lecture by Dr. Foster Cline when my oldest was 3 years old and again about 10 years later. I still use Dr. Cline's advice today! I probably would have been the worst "helicopter" parent if it weren't for this man and his ideas.
3) My Silly Idea is: Begin a tradition of family MOVIE NIGHT. Choose one night where everyone can be at home every week and STICK TO IT. On this night, everyone is HOME - - NO EXCUSES!! Have a sit-down dinner at the table, talk, relax. (New book - "The Table Experience" sites studies that most successful kids in school have family dinners at a TABLE a few times per week.) Then make popcorn. Watch a MOVIE together as a family - - PARENTS must absolutely SIT with the kids and watch it. Remember, NO EXCUSES!! 2 or 3 weeks into your new tradition of "movie night," rent the movie ROCKETMAN. Throughout the entire movie, the main character says, "It wasn't me!" in situations where it's obviously "him." From then on, whenever daughter says "It wasn't me!", the whole family could calmly reply, "OK, Rocketman." Don't make an issue of it anymore. And don't waste any more of your precious energy trying to DEBATE or POINT OUT WHY she's wrong! Just say, "Ok, Rocketman", keep your eyes locked with her eyes. Don't turn your back. Don't leave. Stand calmly and wait for HER response. ((Dr. Cline always said, "Don't waste your breath debating with a teen. 90% of what comes out of their mouth makes no sense." He said it's better to just say, "HMMM." Then stand in silence waiting for the child to talk. This was the best piece of advice I was ever given!!))
4) Just thought of 2 more good books that helped shaped my parenting: "Reviving Ophelia" by (?) and "The Hurried Child" by Dr. David Elkind.
Movies I highly recommend for your FAMILY MOVIE NIGHT are: Akeelah and the Bee, The Princess Bride, Gracie, Enchanted, Sandlot, Peter Pan (the new Peter Pan with cute boy from Australia not the cartoon), Aquamarine, and Ella Enchanted (Last 2 have good strong girl role models - - with message that you may not find "true love" where you expect.). Good luck!!
