Feasibility and Validation of a Smart Changing Pad for Home Infant Weight Monitoring After Hospital Discharge

This pilot study evaluates the feasibility, usability, and clinical utility of the Woddle Smart Changing Pad and companion mobile application for infant monitoring following hospital or NICU discharge. The study also compares infant weight measurements obtained using the Woddle scale with those from standard clinical reference scales to assess accuracy and reliability.
