UNC study: Parenting can override effect of genes in how babies respond
to stress

Everyone gets stressed, even babies.

Now, it appears how infants respond to stress is linked to if they have
a particular form of a certain gene, according to a new study from the
University of North Carolina at Chapel Hill.

Just as significantly, researchers say they have also found that good
parenting – as early as within the first year of a child’s life – can
counter the effect the gene has in babies who initially do not respond
well to stressful situations.
