I actually wouldn't do anything. I'm no dietician, just a mom, but think the more you try to change her, the harder she'll resist. . I would just fix dinner as normal. If she doesn't want to eat it, then she can come to the next meal. A 12 year who doesn't have an eating disorder (and pickiness is not one) is not going to starve. I wouldn't point out that she needs to eat. I wouldn't coax or really say anything other than dinner is ready. If she eats, she eats. If she doesn't, there is always the next meal.
