Does having short temperament or often verbal duals with partner during pregnancy affect Child's long term mental being?

Here is a very interesting article on the effects on anger on the unborn child: http://www.babble.com/pregnancy/anger-affecting-unborn-child/ The article explored the possibility that anger during pregnancy may have some impact on the fetus. Biologically, anger is accompanied by physiological and biological changes: when we get angry, our heart rates and blood pressure go up, as do the levels of our energy hormones as adrenaline and epinephrine are released, contributing to growing tension and causing blood vessels to constrict. This reduces oxygen to the uterus, thus compromising fetal blood supply. And it also mentioned studies that found relationships between long-term anger or anxiety and premature birth (delivered before 37 weeks), a problematic birth or even result in a low birth weight (even when full term). Also, there is a study which found that babies whose mothers experienced high levels of stress, particularly in the first trimester, show signs of more depression and irritability (as well as being colicky). Research has also indicated that extreme anxiety during pregnancy could double a mother’s chance of having a hyperactive child. All these being said, it is crucial to keep in mind that anger is a normal emotion for a person to experience. Especially since during pregnancy, a woman’s hormone levels are changing, it is inevitable for mood swings to happen. Do not be too stressed by these findings. Learn some relaxation techniques if you find yourself flaring up more often than usual. Deep breathing often helps to calm and relax the body when one is anxious or provoked. If you feel up to it, do some light exercises to help keep the body and mind relaxed. Take care of yourself and you will naturally feel better! Seek your partner’s understanding and ask him (and the loved ones around) to be more tolerant during this period. :)
