The problem with charging a half day for 11-2 is that it isn't half a day with the other half being availble for another prospective parent. That to me is the idea of charging half day because it is with the hope of filling the other half. In this case, 11-2 is "middle of the day" and messes your whole day up and you won't be able to fill the early morning or late afternoon so yes they are taking a full day of care up so it should be charged as a full day. The only person it helps by charging a reduced rate is the parent not the provider.
