Charge normal rate?

[Mom of 3]

Same here. Same rate applies. My dc parents took a month off to go to cuba for there wedding and they paid the full month. It is in my contract "That fees are paid no matter if the children are here or not. It is to ensure the space is held".
It is impossible to be able to keep the financial aspect of the business in check if you let parents pick/choose/ or argue how much they pay you and when.
