Our almost 3 yr daughter is starting to throw things and pic up chairs and throw them at home and school as of recently. Nothing has changed and no new stressors. She also thinks it's funny after I discipline her. She even threw the kindle on the floor- just because. So she sometimes does it when she's mad and even just to do it. Is this a phase? I feel like I can handle it at home but it disappoints me she is now doing it at school. She took off her shoes yesterday and swubg them around and it hit one of the other kids. Per the teacher it wasn't that hard but still she affected another kid. There are no reports of her intentionally hurting others- I hope that doesn't change. Not sure where this coming from. No issues with communicating in fact when I was reading her schooleport to her about her day and the part about her swinging the shoes - She even said- yeah I hurt ( and the boys name). So she knows!
