DENVER – Parents, put down your smartphones when you're taking care of your baby.

That's the message from University of California researchers, who found in a study that fragmented care could disrupt a young child's brain development and lead to emotional disorders later in life.

Hal Stern, a Cal-Irvine professor and report co-author, says when moms and dads are bonding with infants, such everyday interruptions as phone calls and text messages can have long lasting impact.

"It speaks to the importance of having, you know, regular patterns in your interactions with your child,” he explains. “And a clear way to do that would be to kind of set the phone aside when it's reading time or play time."

Even though the study's first phase focused on rodents, Stern says it showed distractions can break the consistent rhythms that developing brains need to ensure the growth of robust neuron networks.

He stresses children need greater assurance that when a parent picks up a book, for instance, that time really is reserved for them.

Researchers found erratic care of infants can increase the likelihood of risky behaviors, drug and alcohol use, and depression in adolescence and adult life.

Stern says because mobile phones are so ubiquitous – and bring an endless stream of calls, texts and social media posts – the group's findings are especially important for today's parents.

"As children become adolescents, one might expect effects on risk taking behaviors, and an increased risk of emotional disorders and the like," he states.

Stern says the next step is to see how these discoveries in rodent behavior apply to people.

The team plans to use video analysis of parent care, and imaging technology to measure brain development, to find out if limiting distractions today can help prevent problems for tomorrow's teens and adults.
