I observe the children to determine where they are at developmentally, and then I match the task to that level. I started out by modeling the routine for everyone. After some time, I slowly introduced different tasks at different times. For example, my almost 2 y.o. can independently add hay to the rabbit hay feeder. He will continue adding hay, taking it out, and repeating the process over and over, concentrating on his work until he's satisfied. He's not quite ready to safely remove the water bottle from the hutch and fill it. Therefore, I reserve that task for an older child. On the other hand, the oldest is able to accomplish almost everything related to the rabbit's care and she is interested in doing all of the tasks. More specifically, she wants to make sure they have food, water, and a nice clean environment. She really enjoys taking care of their needs and then playing with them afterward. As a result, she can assist her siblings with anything they need and then do additional tasks that they're not quite up for yet.
