First, don't define this as "stealing". She has no concept of ownership, let alone stealing, so she won't understand when you tell her that she can't steal.

You have to tell her that if you want something that is not explicitly given to her, you have to ask the adults first, and you have to ask the adults first, instead of taking it yourself.

At the same time, when you give her something, you should consciously tell her that this thing is for you, you can use it, that one is not for you, you can't take it directly if you want, so ask an adult.

In children's pedagogy, this is a very important course called "How to get something correctly". When she came that day, she asked, "Can I have another ice cream?" Or, "Can I watch TV for a while?" She learned it when she was young.

Remember never to define this as stealing. It's just that the child has a strong subjective initiative-she thinks she can solve things, so there's no need to bother you adults. Besides, experience has proved that you are likely to disagree with her request, hehe.
