I babysit & regularly play with the children, games, crafts , reading before bed, sometimes bath & maybe do dinner as well if it is an early start. No extra cost it's just part of an evening babysitting, I wouldn't do it if I didn't like children. I would never dream of doing a pay for view TV, just watch the normal one & bring a DVD with me if Sky isn't there. If daytime , then yes going to parks, swimming etc is all normal so is indoor & outdoor play. With a bit of an uplift from night time pay rates. So no you are so not expecting anything abnormal!
