“The more you learn, the less you fear.”

-Julian Barnes

All parents want the best for their children. If you suspect your child is experiencing developmental delays, you might wonder how you can help them get what they need to be successful. It all starts with educating yourself on what developmental delay looks like, what to do next, and how to manage an autism spectrum disorder (ASD) diagnosis, if needed.

We have assembled a collection of resources from trusted sources that you can use to learn more about important these topics and more, plus groups where you can meet parents like you.

This list is a good place to start, but we know there is more out there. Have you found another resource you recommend adding to this page? Email us at or reach out to us on Facebook or Twitter.
