Welcome to the Infant Sleep Information Source

This website presents research evidence about biologically normal sleep for human babies. We discuss how infant sleep may vary due to cultural behaviours and expectations such as what babies are fed, where they sleep, and how we interpret their needs. This information is for a) parents who wish to make informed choices about infant sleep and night-time care, b) health professionals who wish to share evidence-based information with parents about infant sleep.

ISIS does not address clinical sleep problems or provide individual sleep advice and parents should contact a health professional with any concerns about their baby's health. For information about the organisations and funding that support ISIS please see 'About Us'.
