We have tried gentle talking, counting to calm her and talking about it, sending her to her room and then trying to talk when shes calmer, and now calisthenics. However, nothing is working.
There's two things this post relays - one, which I'm sure you've already looked into - is working with the school to address this problem. Sure, sometimes kids don't get along, but most schools look at bullying seriously, and this sounds serious.The other, though, is additional tools to consider to help your daughter. If you haven't already read Greene's Explosive Child, you might give it a shot. While it's a little preachy, many of the tools are wonderful and can help parents navigate tantrums. https://www.amazon.com/Explosive-Child-Understanding-Frustrated-Chronically/dp/0062270451Another tool that can redirect a child that's losing it is a task. If her tantrums, say, involve throwing things, maybe she's in charge of throwing all the sticks and acorns off the driveway into the garbage bin. Ie: 'Hey Jenny, you seem really angry right now, let's use all that energy and get some work done!' Go with her, throw with her, even - if possible - making a game out of getting the acorns into the bin from a distance.I wish you all the best~
