Genetic Stress

Posted:

A new study finds good parenting can help your baby deal with stress.  Researchers discovered some babies carry a gene that causes problems dealing with stressful situations during infancy.  It's linked to aggression and substance abuse later in life.  But after measuring the cardiac response of infants under stress and observing their mother's interaction with them, they found a mother's sensitivity toward her child can actually counter the effect of this gene over time.
