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 happens to my 3 years old too! usually this happens when we force her to do something she doesn't like such as showering and eating vegetable; she will cry out loud that I hate you; but the next hour she would forget this and say I love you again. so Don't be demoralized; she doesn't really mean that.
