Babysitting

So, I'm starting a new babysitting job for one of my close friend's ( Tuesday to Saturday, 9:30 am to 5:30 pm) her son is Two years old. And to be honest I've never baby sat before (except for my younger sibling). I have my first aid. But I was just looking for some activities to do with him during the day, because all I have laid out so far is make him breakfast, lunch, nap time and story time. I'm just trying to make a routine for the hours that I'm babysitting.

I am also looking for any babysitting tips/tricks/advice

(I'm sorry if this is posted to the wrong group I just don't know where to post)
