Material Development Tips/Resources

Hey all! Looking for some new places to get inspiration for materials and finding it incredibly hard to keep making all of these items for kiddos on my caseloads in home that get destroyed, lost, taken with the BTs when they leave the case after a month, etc. It feels like making materials is 90% of my job and I want to be more efficient with it. Any tips/tricks you all have developed, especially for in home cases?

For context i have a current caseload of 15 kids who receive anywhere from 6-20 hours a week of services and I'm really trying my best to make sure they all have what they need within the home for their sessions but it's just so hard to manage it all and I want to develop a better system for them and the BTs/RBTs so we all can thrive. Any advice would be appreciated!
