I completely agree with 5LM. I charge full rate for my stats though. I also charge all part-time children for stats regardless if they are to attend that day or not as well.

I also have never had a parent complain about paying for stats. I did have a dad mention to me though once that Boxing Day and August long are not "real stat" holidays. I think he was upset because his employer didn't pay for those days while he still paid me. He was also one of those "I am paying you therefore you will have my kids every minute of every day that you are open". I also take very limited holiday days (unpaid) and rarely take sick days.
