Study: Genes May Explain Toddler Temper Tantrums

Posted: Updated:

A new study suggests that parents are not to blame for their child's bad behavior. Scientists say it's all in the genes.

Researchers in Canada's University of Montreal claim that temper tantrums  are caused by genetic factors, not bad parenting. The study looked at sets of studies of identical twins and fraternal twins in preschool. The participants were 20, 32 and 50 months old.

It found that the level of aggression in each individual child was due in large part to genetic factors, not the child's upbringing.

However, scientists say that while genes play a factor, they don't always predict developmental problems. In fact, researchers caution about the negative influences from peers and parent upbringing. So again, it's not always nature, and not always nurture.
