A Warning for the Grandkids: Too Many Antibiotics, Too Soon

We’ve long talked about the life-saving role antibiotics have played in modern medicine.

But we’ve also warned about their overuse—especially when they’re prescribed too freely, too often, or when they’re not truly needed.

And now, a new study offers a fresh reason to be cautious… especially for the sake of your grandchildren.

According to researchers analyzing data from nearly 700,000 children, multiple rounds of antibiotics before age 2 are linked to significantly higher risks of asthma, food allergies, and even intellectual disability.

Children who received five or more courses of antibiotics in those early years had:

• A 52% higher risk of developing asthma
• A 53% higher risk of developing food allergies
• And a 73% higher risk of being diagnosed with intellectual disability

Even kids who received just one or two courses showed elevated risk.

These aren’t mild consequences. Asthma and food allergies can disrupt a child’s daily life, trigger ER visits, and lead to lifelong health challenges. Intellectual disabilities can change the trajectory of a child’s development, education, and future independence.

And while antibiotics are sometimes necessary—such as for confirmed bacterial infections—this study reinforces a critical message: We must use them wisely.

The good news is, there’s plenty you can do.

As a grandparent, you’re in a powerful position to share wisdom and speak up. When your children or grandchildren are prescribed antibiotics for minor illnesses (like colds, which are viral and don’t respond to antibiotics), encourage a second opinion or ask whether a “watchful waiting” approach is appropriate.

Most importantly, encourage preventive health:

• Support strong immune systems with healthy diets, plenty of rest, and physical activity
• Help kids avoid unnecessary exposure to sick individuals
• Educate your family about when antibiotics are appropriate—and when they aren’t

Because sometimes, doing nothing is actually the best medicine of all.

In the words of the study’s authors: “This study contributes to mounting evidence for long-term harms from early-life antibiotic exposure, underscoring the need for judicious antibiotic use in infancy and early childhood.”

Wise words—and worth remembering.

To limiting antibiotic usage,
