Client coming off mat leave wants to change hours

[Busy ECE mommy]

Absolutely not!!! Did she just assume you’d say yes?
It would be one thing to do it once because she has an early appointment/meeting etc( with extra fees) but to do it permanently is a no-go in my books.
It’s a slippery slope... why should one family be allowed special treatment over the others? The expectation will be that you will bend your rules again and again.
I charge $1 minute per child for early or late fees per child, so if you don’t have something in the contract about early drop off or late pickup, I’d get it in there now, and make the fees steep!
