Client coming off mat leave wants to change hours

Saying that it's only a half hour, and asking if I was prepared to lose her family if her schedule didn't work out.

It's not only half an hour.
If they are full time client's, 30 mins a day equates to 2.5 hours extra a week.
Assuming you take 10 days vacation, that means you work 50 weeks a year.
2.5 hours a week x 50 weeks a year = 101 extra hours.

That's about 10 full days.

If you explain it that way - 10 full days x 2 children = 20 days of care she's getting extra. Then Im sure she would understand why an extra fee would be required *if* you were willing to do it.
