Would you ignore your 6 year old screaming in the middle of the night for ice cubes in her water?

My 6 year old is an Angel in public and at school/with family but at home with me she is a nightmare sometimes.

She is very whiny and demanding. I've explained things to her and it's like it goes over her head. Like why we can't buy a toy every time we go to a store, why we need to be grateful for what we have, how she needs to be respectful.

When she gets mad she sometimes hits me, or threatens to hit me. I had to cut ties with our cleaning woman because our daughter threw a fit in front of her and didn't feel like making her bed anymore because someone else would.

I showed her the importance of cleaning our space, being thankful, etc.

But she doesn't listen.

When she doesn't get what she wants, she often whines, stomps or pouts. Sometimes she gets mad and lashes out verbally or physically. Usually I try talking to her then put her in timeout if it escalates. I've tried deep breathing exercises, sensory toys, etc, nothing works.

Last night she woke up screaming because her ice cubes melted in her night water. She wanted me to get her ice cubes at 3 AM. I told her no, she can wait until morning and if she runs out of water to wait til morning. Im sick of her demanding things from me.

She said this morning "im going to make a list of things you do with a check mark next to it."???

HOW DO I RESPOND TO THIS? Im going nuts!!!
