Up-to date research-based information on infant sleep, safety, and development from the Infant Sleep Info Source website (www.isisonine.org.uk). This informational app explains how and why babies sleep as they do, and explains the reasons for safe sleep guidance. Includes an interactive bed-sharing safety tool, an optional sleep diary for your baby and links to info sheets and other web-based resources. A great teaching tool for health professionals and resource for parents who want to make informed choices about topics such as co-sleeping, sleep training, and SIDS. The Infant Sleep Info Source (ISIS) was created by Durham University Parent-Infant Sleep Lab, with La Leche League, NCT, and the UNICEF UK Baby Friendly Initiative, funded by a grant from the ESRC (Economic and Social Research Council). Also endorsed by Association of Breastfeeding Mothers, Lactation Consultants of Great Britain, and the Breastfeeding Network.
