I also used to do half day and full day rates. Now I only offer full day. Realistically, you're not going to be able to fill that other half day with another child, so it's money out of your pocket to accommodate someone else's schedule. You can't even count on regular hours as he's shifting it around. If a child attends my daycare for 1 hour or 10, it's the same fee....no exceptions. That would be my recommendation, but I can probably bet you're second guessing yourself because you don't want to take advantage of a client. Trust me....you're not. This is a business and any large daycare would have the same policy. You need to look after your own interests.
