My 2 year old literally thinks she’s entitled to have everything

As long as throwing a fit works, she’s going to keep doing it. So at some point you will need to bite the bullet and just let her throw the fit, and see that it doesn’t work. Just be warned it will get worse before it gets better, so stay strong!

... Some people never grow out of this phase.

a person's personality is basically a set of strategies to respond and fulfill our needs. every kid is a scientist testing behaviors and carefully taking notes of which leads to a result and which doesn't and when we get older these strategies become who we are. hopefully, our surroundings and family will respond to us in a way similar to how adult life will respond to us and then these strategies that we developed as kids will work in the "real" world and we will be well adapted individuals. now, about you and your kid, every time you let her have her way when she is acting in a way that is selfish and socially unacceptable she is learning from this that this behavior works so she will continue to use this strategy. it is really not a service to you or her to do this because it will prevent her from developing temperance and awareness of others and encourage personality traits that people in the "real" world will not like and she will find it hard to make friends. First thing to teach her, by actions more than words, is that fits get no result, she MUST think that fits don't work so she can abandon this strategy and learn that being considerate, patient and aware of other peoples needs DOES work. She is not an adult and should not be judged for these behaviors, simply create a environment and a relationship with her where bad behavior doesn't get results so that her "inner scientist" writes off these behaviors as not efficient and useless.

Lol.... when my niece was little, she quickly came to understand that my sister would not be swayed by her fits. Because after the first few, when she still decided to break into hysterics, my sister would simply ask her, “What do you get when you act this way?” And through her adorable, tear streamed face she would cry out, “ABSOLUTELY NOTHING!”

Let her throw the fit. Just stand and watch her to make sure she doesn't get hurt. When she pauses to take a breath, ask her if she is done now, because if she is, then we can go have some fun.

I am not a mother but from what I heard others say, you can't give in when she has a fit because she will keep doing it and she will also grow up that way. Start from home so it isn't embarrassing and tell her no at home. If she throws a fit, let her throw that fit, when she calms down a bit, explain things to her as to why she cannot behave that way.

Welcome to the terrible 2's :)

Are you gonna put her on 1/10th ration and a beating a day? That'll show her.
