My advice would be to start by seeing what preschool programs, if any, are offered by your local public school district. Based on those zip codes, it looks like you might live in the Brandywine School District, which offers several early childhood programs that are free for income-eligible families. To learn more, contact the district at 302-793-5000 or visit the district's website.
I would also recommend that you look into Head Start, a national program which provides free early childhood education services to families who qualify. You can find programs near you using the Head Start Program Locator.
While private preschool programs require tuition, many also offer scholarships and financial aid. If you find a private preschool program that interests you, it's worth reaching out to see what financial aid opportunities might be available.
A great way to see what public and private preschool options exist in your area is to use Noodle's preschool search tool, which allows you to search by age level, cost, location, program type, and more. You might also find it helpful to browse Noodle's articles and advice about finding a preschool.
Hope this helps, and best of luck!
