How do you word a contract so parents know I expect the same rate of pay even if a child is napping or in school? I set my rate based on the total number of children I'm responsible for at any time during work hours. For example my rate for two kids is $16/hr. I will have the baby all day and the 5 year old half day. What words should I use so parents don't think I'll drop to $14/hr (my single child rate) for half day?
