I heard "ignore the tantrum, not the toddler" and that really helped me. It took a lot of willpower, but trying to communicate in a level-minded way helped my daughter bring it down a notch lol
It's real hard. I have no advice to give, but to wait it out. Less verbals, more non verbals.
I don’t think you need to be concerned. This is a big independent stage where they want to do everything but sometimes they can’t and it’s probably very frustrating for their little minds. Of course you will have to deal with it with whatever you feel is best but I would do your best to stay as calm as you can. I have to tell myself constantly “if you can’t keep your cool and not freak out, how can I expect her to do the same?” It’s such a hard stage with emotions, wish I could help more. Good luck, this won’t be forever!
