Some days it can exhausting as you are constantly on the go and have to make really quick decisions and solve problems on the spot. It is really dynamic work so you have to adapt a lot to the situation which can be stressful. Also, something no-one talks about is how as you change groups every few weeks, it can be emotionally overwhelming when the kids leave and new ones come to replace them but that obviously depends on the type of person you are and how much you are able to bond with the group allocated to you.
