Nervous about going back to work after the holiday break

My break started on the 21 of December for the holiday season and I go back tomorrow. I work as an Educational Assistant (meaning I work with students with special needs). Specifically in a kindergarten classroom. I have a new student coming in tomorrow. He’s known as a runner, is quick and very curious. I’m just nervous because of the fact that I’ve never worked with a student like this before. Any encouraging words would be helpful
