My little girl (nearly 4) has some big emotions. She struggles with getting to words and has a complete shut down when she's going through a tantrum. She screetches and wails and starts screaming. I've tried asking her why she's upset but she doesn't really make any sense when we are in the thick of a tantrum.

What are your strategies for dealing with tantrums? Is there any way to de-escalate or do I just let it run its course?

How much of this is normal for her age?
