Sarah's favorite phrase is "Nooooo, mine!!!" and run away. She's getting better about giving things back when I ask her to, but then Katie takes things away from her, too. Their latest game is sneaking into Emma's room when she forgets to close the door and take things from there. Both Katie and Sarah enjoy playing with the same toys, which isn't helping, but it also forces them to share, so Sarah can't be so grabby. I wish I had more advice!
