One of my favorite resources is the website, the Inspired Treehouse!
The authors are pediatric occupational and physical therapists who are dedicated to helping children overcome common developmental roadblocks using movement and sensory activities. The website offers information on developmental milestones, activities, and resources to help parents, therapists and educators advance the well being of the children they care about!
Plus, the authors are super generous in giving away content-filled blogs and ready-to use strategies to develop all aspects of your child from core strength to fine motor control. They also offer paid options such as a Summer Activities Pack (only $4.99) with daily activities for promoting core strength, gross and fine motor skills and sensory fun!
