There are homeschool groups for all sorts of different age ranges. For instance, from our
California groups page (look for the word preschool):
Considering Homeschooling Ministry - Morningstar Educational Network
A Christian ministry helping parents with babies, toddlers, preschoolers and with older children discover the blessings of a biblical home education. Free DVD and brochure, mentors and meetings.
Orange County Exploring Homeschooling
A chapter of the national Exploring Homeschooling. Our organization offers weekly field trips, classes, nursing home ministry, park days, entrepreneur club, and other fellowship opportunities, mainly for the parents of babies, toddlers and preschoolers who are looking into Biblical homeschooling. We also have veteran homeschoolers share at our monthly meetings.
Sierra Nevada Homeschoolers Group
Our group is welcome to any homeschool family from El Dorado County and Sacramento County (or outlying areas) that wants to network with others. Meeting weekly at different locations along the 50 corridor, our group can help enrich your homeschooling experience. We have members of every age range from preschool to high school, and meet for social activities, small group classes, family field trips, and exchange of ideas and educational support.
