At the most it would be a 6 hour day. On days where I was there longer we'd work out a set rate for the day rather than $15 p/h. I'd do whatever was required, depending on the age of the child/ren. If it were a little bubs that is generally easier; bathe, feed, change, etc. Older kids, make lunches, or feed brekky, play, put down for naps, go to parks, help with school work (if old enough). For night jobs, help mum cook dinner, bathe kids, stories etc. Just basically an extra pair of hands.
