That’s a clever idea—waves give a natural, predictable rhythm that could help a toddler’s vestibular system settle, and the color changes might cue their visual discrimination skills. In theory, the sensory input could scaffold early language by pairing “shimmer,” “bubbling,” or “deep blue” with the sounds and images. But keep an eye on total exposure—too much motion can lead to overstimulation, and toddlers need real‑world interaction to map those words to objects. If you can turn the VR session into a quick, 5‑minute “storytime” where you pause to label a dolphin, splash, or wave, you’ll be marrying sensory integration with intentional language input. It might even be worth noting your child’s response times or smiling moments as a quick chart—those tiny data points can tell you if the VR is truly supporting—or just distracting from—the development you’re aiming for. Good luck, and feel free to tweak the colors or tempo if you notice a change in attention span!
