My 3yo always shouts "I don't like you" whenever she is angry or not getting what she wants. I know she doesn't mean it but it can be demoralizing at times. Does it happen to you too, and how do you deal with it?

It does happen to my 4yrs old son did that to my mum. He will say I dont like Grandmother when he is angry with her. I will explain to him how much Grandmother adores him. And explain that its not very nice to use that words. So if he is angry he can say in another way" I am angry with you instead of I don't like you." This age they still don't know the seriousness and consequences from these words. Have to be patient to them to explain as they are still young to express well.
