The Little by Little (LBL) program is an early literacy program provided through the WIC program, a federal program that serves low-income pregnant women, infants and children from 0-5 years of age. The LBL program offers WIC participants’ handouts about child development milestones, information on activities parents can do with their children, children’s books, and safety items (such as outlet plugs, bath thermometers, safety scissors, etc.). The LBL implementation evaluation was designed to help Public Health Foundation Enterprises (PHFE) WIC program managers monitor how LBL was conducted across the different WIC Centers. ETI’s evaluation of the Little by Little program included four site visits for each site (3-4 hours per site visit), site observations of the staff that deliver the LBL program, site summaries describing how the program is delivered to participants (including the model used, how the materials are introduced, and how they store their materials), and the distribution and collection of surveys given to LBL participants to measure how the program has impacted their parenting as a result of participating in the LBL program. Site reports for each of the seven sites were due a month after the last site visit for each site. An end of the year report comparing all ten WIC sites, including the three observed in 2014, was due September 2015.
