I’m Catherine Landis, the founder of Oat What Fun. I have a M.S. degree in Education, taught middle school reading, and was a preschool educator and director.

I am a mom of three children and through all of my personal experiences, I have become a natural living expert who is passionate about helping families create healthier homes.

Oat What Fun was created for my son, William, who went on an extensive medical journey from ages 2-4. He was ultimately diagnosed with Crohn’s and put on multiple immune suppressing medications, but I begged his doctors for an alternative treatment plan. His doctors told me I could explore natural living and change our lifestyle. There were no guarantees, but I saw a beacon of hope and decided we had nothing to lose.

I spent countless hours researching all natural living and tackling every aspect of our lifestyle by swapping out personal products, cleaning products, plastics, and foods for natural alternatives. Through this process, I could not find play products that met our all natural living standards. I know as an educator how important play is. I spent the next five years developing safe play products. Oat What Fun was born. William’s Crohn’s is in remission, and my entire family lives in a happier, healthier home.

Now I am on a mission to spread the joy of safer, natural play products to all children. Let’s create healthier homes together!

From my family to yours,



1. encourages speech development
By engaging in hands-on play, children learn how to describe what they’re doing and how it feels, which leads them to using more descriptive words to communicate.

2. Develops fine motor skills
Think of hands-on play as exercise for children's hands. This type of play focuses on building, pouring and mixing, which allows children to use small muscle groups and coordinate movements. All of this leads to developing strong hands which allows children to begin handwriting, learn to tie their shoes, zip a zipper, open an apple pouch, and more.

3. stimulates cognitive growth
With hands-on play, children are working on problem solving skills. It encourages them to explore how to play and engage with different experiences as well as how to maneuver challenges they encounter. An example is how to pour sand from one container to another. All of this is problem solving and thinking about how things work, which results in cognitive growth.

4. has a calming effect
Hands-on play is a great resource for teaching children how to regulate their emotions. Playing with different textures with hands builds nerve connections to the brain resulting in children feeling calm and soothed.

5. inspires social interaction
By engaging in hands-on play with siblings or peers, children begin to develop social skills. They’ll learn how to communicate, how to troubleshoot problems and learn to adapt to how others play. Hands-on play is something every child can engage in and play together.
