How can I thank my coworkers for having to do my job while I’m injured?

I’m a daycare teacher and this is the second time I broke my arm and now my hand and am having to have my coworkers do my diaper changes (each of us 3 girls have 4 diaper changes to do, and now since I’m injured AGAIN, my two coworkers have to take two of my kids potty changes each, so they will have to both change two more kids each for a whole month since I’m on a 5 pound weight limit so I’m unable to do my diaper changes.. how can I thank my coworkers for having to take over doing my kids potties since I’m unable to for a second time…
