(*Adding this: sorry to ramble but I forgot something: when my girl was a little older, we taught her that, like adults, we ALL get grumpy and want to yell. Fine. BUT, she can go in her room and yell it out all she wants... this is her "safe" zone. It's okay. THEN when she feels better, she can come out and we can talk about it if need be. BUT that although it's okay to get grumpy, like adults, we should TRY OUR BEST not to take it out on others... this is "not" okay...we are a "TEAM" and should try to be so. THIS approach helped our daughter, and at the same time, it didn't get her all pent up when she felt like screaming.)
Okay besides the typical "this is the terrible 2's" ordeal... well, if she is this "stubborn" as you say....just try NOT responding to her... or, respond to her in a "whisper." Many teachers use this technique.
You state your point to her....then, walk away. Do not escalate your voice... keep it low. Make eye contact with her, say "no" or whatever it is you need to tell her. Keep it succinct and plain, without being too "wordy", and then walk away. KEEP doing this. It WILL be repetitious, but that is how it is.
Or, tell her "Mommy's ears don't work when you yell...."
Also, sometimes they do this because they need more attention. Or, because they are frustrated. Or because as is with development...and their age... they simply do NOT know how to communicate yet... civilly. And also as Deanna Leigh mentioned... I, from a young age, ALWAYS taught my kids about "feelings" and the words for it, and that is it OKAY to talk and express themselves. This in the long run, will help them to be much more "aware" of themselves. My girl, from such a young age, is very aware of her feelings now, and of others. It is a good thing to teach them.
It WILL continue... and actually, the 3 year old phase is harder than at 2. The "tantrum" phase actually does not stop at 2 years old... it continues up until about 5-6 years old, then it will segue into other things and manifestations.
But yes, they at this age, need to learn "boundaries." So, even though you may feel like a broken record... just keep at it. As long as your methods are age-appropriate and not hostile toward them.
Lots of times, they are just testing you too... and they are trying to be more independent and have their own sort of "control" over the world.
No, sorry, it will NOT stop. This is the nature of a child... ANY child. But, when she tantrums, simply do not give her what she wants. AND, you will have to bear with it... because once you tell her "no" the child WILL have a melt-down...but if you keep to your stance.... it WILL deflate. THEN, when she deflates... THEN talk to her... calmly and with "cause and effect" examples and praise (for when she is trying).
For when she IS TRYING HER BEST (even if it is "not" as PERFECT as "you" may want her to be), give her praise. A child cannot be perfect.. .and sometimes, just this feeling of "having to be" perfect, will frustrate them and throw them into a tizzy. My daughter was this way... so we had to HELP her understand that we love her no matter what, and that we don't expect "perfection", but just trying her best. THEN it became "attainable" for her.
No matter what you try... it HAS TO BE 'ATTAINABLE' for the child. Or, they will always "feel" and be, disappointed. So then they won't "try" at all.
When my kids went through this, and per their age, I simply said "no, stop it..." and then kept my eye contact on them, made sure they look at me... and then that's it. Then, they will normally scream or tantrum because I told them to stop or took away an object.. .but so be it. But within 2 minutes, they ON THEIR OWN, would deflate and stop their tantrum... because they knew I made my point and that is it. I did not give in.
It's hard and usually irritating to have the tantrum thing going on... but well, they are just a child. It'll happen at all ages. Not just now. AND, children this age DO NOT HAVE IMPULSE control, yet. FULL impulse control does not "develop" until about 3+ years old. So, a parent will be repeating and repeating and repeating the same thing over and over. A child takes their WHOLE childhood to get it right... and to learn.
But yes, teach her "boundaries." That is what we are there for... and giving her comfort too. I say this because with my daughter... when she is needing more of "me" she sometimes gets very moody and cantankerous... and yells. So, I do the usual verbal routine with her... then if that does not work... I go up to her, hug her, carry her into my lap and wrap my arms around her... and just stay silent and have a "moment" with her... and within seconds, her body will "melt" and be less tense, and she will deflate. And she will just cuddle me and she will feel better. A child just gets frustrated and they dont' always know "why." So keep that in mind too... many times, they don't even KNOW why they are yelling... and just cuddling them can help.
Just see what makes your girl tick... and gauge her.
All the best, I know, it's not easy... I just had a battle with my kids yesterday! Phew!
Good luck,
Susan
