Bad start to the day :(

[Crayola kiddies]

I regret to inform you that due to a general air of disrespect towards myself and my business I will no longer be able to provide care for xxxxxx. The last date of available care will be xxxxx.

Make sure you give the proper amount notice as stated in your policy book and after you receive your fees for that period(assuming you receive fees in advance of care). Always speak to the parent and explain that you are terminating and why and then give them a letter saying "this is the writen notice for your records"
