Lexi just started 2nd grade this year (turns 7 in a few weeks), and she has also turned into a major Princess. She is being mean / rude to her 3 year old brother. This past weekend threw a full on temper tantrum when she didnt get her way at a birthday party. Extra Whiney / Clingy.
Not sure what to do. We have tried talking to her, taking things / activities away, and it continues to happen,
