I don't know how much you charge a day but lets say for example you charge $40 dollars a day and have 5 children in your care. If you give them a free pass to take complete advantage of this, which they absolutly will do, then you are potentially losing 200-400 a month if every family uses 1-2 sick days per month. That is absolute madness. Are they going to pay you 1-2 days per month for being sick?? They would laugh in your face if you asked for this....I strongly advise you not to do this. Otherwise you are opening yourself up to be taken for a fool and it is a significant dent in your income and could leave you short without any notice. Then I fear you would be full of regret and resentment for making this decision.
