Well thanks everyone ! Nice to see all you point of views. This family are 3 days/week attendees. The way I saw it is that they started Sept. 4th then they should not be paying for labor day. But then I tought wait a minute ... The child starts on the 4th because I am closed on the 3rd right ? Anyway, I still decided not to charge them since well ... it just does not seem right. I did not charge this family a holding fee either so why charge for that day after holding the space for FREE for 3 months. ( Yeah I know stupid now ) Next year I will be charging holding fees.

Mama Mia, In your case I think I would be inclined to charge them. The child is already in your program...
