Q: When our daughter, an only child, turned thirteen and entered the 8th grade, it was like a switch was flipped. Almost overnight, she went from being a sweet, respectful and obedient child who had never given us any serious problems to being petulant, sassy, and often belligerent. She wants nothing to do with us anymore and makes that perfectly clear in often very hurtful ways. She stays in her room, on her smartphone, most of the time, often refusing to even eat dinner with us. We tried taking her phone away, but she threw such an out-of-control tantrum – shrieking, throwing and breaking things, even – that we became concerned gave it back to her. Her grades are beginning to suffer as well. We just don't know what to do. Should we perhaps put her in counseling with someone?
