... I'm having a wobble with how I'm dealing with them.
She's very bright and talkative and extremely high-energy. However, within the last couple of months has started to have tantrums akin to my 2yo's: complete with screams and foot-stomping. It sounds awful. God knows what our neighbours must think.
Being back at school has been great for her and generally, her behaviour has improved since returning a few days ago.
However, she still has these tantrums. I've recently started to use a star chart where she gets a golden star for good beahviour and a red star for bad.
She's just received 5 red stars on the strength of one tantrum 
Is it counterproductive to give red stars when this seems to make her tantrum worse? I have done this in an effort to stop me from shouting - this was what I was doing before and just felt like such a shit ...
If it's any use, I know she gets frustrated with her 2yo dsis, and she regularly wakes at 5am (regardless of whether I put her to bed at 7pm or 8:30pm).
Help, please!
