some reactions from children are pure emotion. at that point that's all the know and they're bodies react. she feels rage, pain, anger, etc...she reacts to that physically. some actions are not "learned" (i.e. balling fists in rage and screaming, throwing self on floor and lunging towards someone)
she does sound advanced so is picking up on and experiencing more at an earlier age. soon you'll be able to reason with her and it will get easier...you can start breaking the the pure emotion with words that attract.
i think it's imperative for you and her that you have other ppl dealing with her from time to time as well. you've set your bond. she knows who you are in her life. it's important for both of you that others be allowed to temporarily care for her...especially daddy! he should have alone time with her every evening to bond i think.
i'm not a professional. however, i went thru this with my daughter and it was the only way...time will help with reasoning and calm the emotional outbursts. also make sure her time is structured to induce more calm periods. but you have to work with husband on getting him involved. give him the advice he needs to deal then let him do it...on his own. he needs that special time with his daughter, and she needs that time and bond with him...it's imperitive, i think.
obviously, i'm no professional. however, i'm a professional mom and caregiver....one that's been where you're at
gl and let us know!
