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?

No he is not saying that and if he says so I will tell him that it was wrong and I will explain to why it is wrong to say that and I will explain to him why he couldn't get everything he wanted so I cannot spoil him
