My daughter has been going thru similar, without the tears in public, for about three years.
She is 11 now.
Dr says it is her hormones becoming aware and activating for puberty. And also the fact that anything is magnified at this age, especially if they were more mature as little ones. Their emotions are far behind the intellect.
To punish one for something so natural would be totally out of bounds!! And I don't believe that crying in public is an awful thing! Sure, it is in-apppropriate at times, but not awful.
When a child does this, they need attention in some other area of their lives and do not know how to express it.
Since I have set aside more time[what seemed almost an un-reasonable amount at first] for my daughter. to talk about becoming a lady, to talk about what and what is not proper for a lady to behave and also fun time for just her and me; it has helped immensly.
to arbitrarily decide that this is behavior that is just "spoiled child" like stuff is not fair. You don't know what goes on in their minds.
You need to get to the core. By spending more time and talking.
Some kids need more time than others. Just a fact of life.
She was re-directed and kept so busy, she didn't have time anymore to think about such things. Now, without fail, once every three weeks or so, she goes at it again. Every little thing bothers her. I merely say...hey---go do some deep breathing,... you are becoming a lady. Remember what ladies do!
And she will go to her room and gather herself together. I taught her breathing and relax techniques,...she comes out feeling and looking and ACTING better.
Re-direct her stories into writing. Every week, my daugher has to come up with ONE story ON PAPER. And it has to be two pages,...corrected and edited by us together. Then she can read her story to all. This is it. She is allowed only one. , so she is told it better be a whopper. But this is where stories belong. And she can show them to her grand kids someday. They belong no where else.
And I did tell her drama is for the stage. Either put it on paper or save it for a choice as a career later in life. If she doesn't, then she has to do extra chores or whatever I choose.
Hang in there mom. It really isn't so bad. Just guide and re-direct.
