Is Your Child Sick or Injured?

Is your child sick or injured?

Use Our Symptom Checker for Advice 

Our symptom checker offers educational information on various conditions, and provides advice regarding home care or first aid, when appropriate, as well as instructions on when you may need to call your provider, call 911, or go to an emergency department. It also offers dosage tables for common over-the-counter drugs.

The information in our symptom checker is designed with patient safety as the highest priority. Each care guide is reviewed by physicians, specialists and nurses for accuracy.

If you need additional advice regarding your child's sickness or injury, please contact your provider.

Children's Pavilion - Opening in 2019

Designed to meet the needs of kids, their families, and the people who care for them, this state-of-the-art facility on our downtown Boise campus will more than double our clinical space and improve vital services that keep care close to home. It will bring most of our pediatric specialists and services under one roof, allowing us to provide care more efficiently and easing the burden on parents and kids who will now be able to see several providers in one location in one day.
