Historically, FLE has been incorporated into a variety of educational and social enterprises (Lewis-Rowley, Brasher, Moss, Duncan, & Stiles, 1993). This is partially due to the multidisciplinary and multi-professional nature of FLE (Arcus, Schvaneveldt, & Moss, 1993; Darling & Cassidy, 2014; Duncan & Goddard, 2017; Lewis-Rowley et al., 1993) yet it is a unique profession (Hans, 2015). Before we discuss how a FLE approach within the EHS HV program structure could advance the study and practice of the interface between FLE and EHS home visiting, we will briefly remember the past and provide an overview of key events and cornerstones that promoted the evolution of FLE.
