Provided are mechanisms and processes for determining an infant's developmental age relative to biological age. In one example, a system includes an infant monitoring device and a monitoring hub. The infant monitoring device includes sensors that gather measurement data associated with the infant. The monitoring hub receives the measurement data and analyzes the measurement data in relation to a development model obtained from a remote platform to determine a developmental age for the infant. The monitoring hub then provides a comparison of the developmental age with a biological age of the infant, where the biological age is obtained by manual input by a user at the monitoring hub.
