Shouting at a child/spouse

Curious to hear what everyone would consider to be unacceptable “shouting” at your child or partner.

We all know that shouting at your child or partner is far from ideal but are we all talking about the same thing?

For example, I think there would be total agreement that screaming “I hate you and you’re worthless” in anyone’s face is abusive and unacceptable.

But, if you were to raise your voice to ask your toddler with an obvious air of frustration (having asked a hundred times calmly) to please “come here so I can get your dressed” etc - would you consider that unacceptable shouting? Or just ‘less than ideally handled but not going to cause the child any harm’. And what about if this were to happen for a prolonged period of 5 mins where you’re consistently getting frustrated in a raised voice?

And what about if they’re about to do something dangerous? I will absolutely yell in this instance to provoke a faster reaction even if it just to pause them in their midst so I can run to my child and stop her from going into the road/falling down the stairs or whatever.

I just hear so many people say that they NEVER shout at their partner/child but I don’t really understand how. Are we talking about different things??
