A developmental psychologist suggests the best way to raise resilient children.

Every parent makes mistakes. Don't beat yourself up over it.

Aliza Pressman, a developmental psychologist, advised on teaching children resilience at the Aspen Ideas Festival on Monday.

"According to Pressman, being a parent requires bravery, and there is no way to avoid making mistakes. The best we can do is to view those mistakes as an opportunity to model bravery for our children. Pressman is the co-founder of the Mount Sinai Parenting Center and the author of the book "The 5 Principles of Parenting: Your Essential Guide to Raising Good Humans.""

Instead of advising kids to stop worrying or relax during challenging times, it's more important to assure them that they are loved for their true selves, and that it's okay to share their emotions and be themselves.

Helping children develop resilience by teaching them to manage difficult emotions in stressful situations is crucial for their future happiness and success as adults.

"We absolutely need some stress for resilience building," Pressman said.

When parents help, stress can build resilience

A child who can recover from a stressful or disappointing experience, such as failing a test or having a disagreement with a friend, is a sign of a healthy and resilient personality, according to Pressman.

Resilience is defined as the ability to recover from adversity, including setbacks, stress, and trauma, as she pointed out.

It's important to note that constant stress may not be healthy. In most cases, simply talking to your child about their feelings and showing them love and support can prevent stress from becoming a serious mental health issue, as Pressman suggests.

""Being present more often than not is the key," she emphasized, explaining that it's not about experiencing toxic stress, but rather about being mentally and emotionally available for your children."

Experts suggest that children can develop a "growth mindset" by openly discussing their mistakes, how they overcame them, and what they learned. This can help normalize and reduce the pressure of overcoming difficult situations, according to Mary C. Murphy, an Indiana University psychologist who wrote for CNBC Make It in March.

"Often, starting something valuable requires effort, particularly initially," Murphy stated.
