Overview

The goal of this clinical trial is to evaluates the usability, tolerability, and clinical accuracy of the JessieHug device, a wearable medical device for newborns and infants that collects physiological data. The main questions it aims to answer are:

• Is the device easily usable for parents of newborns and infants?
• Is the device tolerable when worn by infants and are there any safety concerns?
• Is the device able to collect clinically accurate physiologic data compared to a FDA-cleared reference device?

Participants will:

• Place the JessieHug device on their infant two times a week and complete surveys to assess usability, tolerability and safety.
• Have one session where the JessieHug device will be worn at the same time as reference device to determine accuracy.
