Navigating Your Birth to Three Journey, Together

Delaware’s Birth to Three Early Intervention Program (B23) supports families with infants and toddlers who have, or are at risk of, developmental delays or disabilities. Together, we help your child reach their full potential through assessments, personalized plans, and expert guidance.

What We Do

Help Families

The Birth to Three Early Intervention Program helps families by giving them support and resources they need to understand and guide their child’s growth during their first three years of life.

Identify Delays Early

The program focuses on  identifying developmental delays or disabilities early on, so children and their families can get the services and support they need to enhance development and the family’s capacity to work towards their best achievable outcomes.

Work Together

The Birth to Three Early Intervention Program brings families, healthcare providers, and community resources together, creating a team that supports children in reaching their full potential.

Ms. Rachel and Delaware’s Birth to Three Early Intervention Program have joined forces to support your family on the journey through early childhood.

About Ms Rachel

Rachel Griffin Accurso, known online as Ms. Rachel, has her Master’s in Music Education from NYU and is working towards her second Master’s in Early Childhood Education. She is a New York City preschool teacher turned YouTube and TikTok star who is making a big impact on children around the world with over 2B views on YouTube alone. Alongside her husband Aron Accurso, the pair produce, star in, and distribute a popular YouTube channel for toddlers and preschoolers with educational videos and music classes, SONGS FOR LITTLES. The two began the show after their son, Thomas, was diagnosed with a speech delay and they struggled to find proper tools to encourage his language development. While Ms Rachel is the star of the show (with help from puppets Georgie and Herbie, operated by Aron) there is a cast of musical and technical professionals who bring it to life, led by Aron.

Ages and Stages Questionnaire


The Ages & Stages Questionnaire (ASQ) takes about 10-15 minutes to complete and helps you learn about your child’s skills in communicating, problem-solving, moving, and interacting with family and friends. Completing the ASQ helps you understand your child’s strengths and areas for growth.

If you’re concerned about your child’s development, fill out the referral form to begin your journey with the Delaware Birth to Three Early Intervention program.

You can refer on your own.

Schedule with Our Team

After you submit the referral form, a Birth to Three team member will contact you. During this time you will be provided with more information about the B23 program and what the next steps are on your B23 journey, which may include a multi-disciplinary evaluation for your child.

Work with Our Team

If your child is determined eligible for services, we’ll work with you to create an Individualized Family Service Plan (IFSP). This plan outlines the goals, support, and services your child will receive to help them achieve their highest potential.

What Our Families Are Saying

Molly M.

My family’s experience with the Birth to Three program has been fantastic. Both of my children who participated were evaluated quickly after the referral and received exceptional services from their therapy provider as well as from their Family Service Coordinators. All of the therapists communicate very well with my husband and I so that we can carry over the techniques at home and reinforce the same skills. We truly appreciate this program and everything it’s done for our children.

Jen R.

Our Birth to Three Family Service Coordinator was a vital partner as I navigated the early years of my daughter’s disability. They educated me on my rights and resources and coordinated services like Speech and Physical Therapies. I am forever grateful for the helping hand during a time that felt so uncertain.
