4 year old tantrums

[KipperTheFrog]

My 4 year old DD still has the most awful tantrums. Any time she doesn't get what she wants, or things don't go her way she screams. And I mean SCREAMS. People must think I'm hurting her or something. There's no reasoning with her when she gets like that, she won't listen till she's stopped screaming, which can take a while!
Once she's calmed down we can talk about what happened, we'll explain why she hasn't got what she wants, but it doesn't stop it happening again.
Example: she wanted a snack yesterday after school. All I had in the car was breadsticks, we were 5 minutes from home. I offered the breadsticks, she said she didn't want those so I told her that's all I had but we'd be home soon. She screamed the whole way home then had the breadsticks.
Anyone got any ideas how I can help her to manage her emotions better?

No idea sorry. She sounds just like my DD was (still can be occasionally).

Hopefully, someone will be along soon.

Maybe try setting some boundaries? She's at an age where you can tell her you're not going to allow certain behaviours. "It's ok to be upset about things, it's not ok to scream and hurt my ears." She's not a baby anymore where they scream because they can't communicate so her doing it is purely to make her point that she's mad. I would suggest be a little stern with her.

Thanks for the replies.
lovely we already do that. We ignore her when she's tantrumming. She doesn't get her way when she has a tantrum. Doesn't stop the tantrum from happening. I can't forcibly stop her screaming

Ah. So tough.. :( I know what you mean. When they're in the moment, nothing works. My son is 15 months and if we're out at the shop and sees something he wants, he'll scream his lungs out. It's really embarrassing.
