How should I tell her?

[Sandbox Sally]

This past spring, I found myself in this exact position. I wrote a letter to the parents:

Dear Parents,

As you all know, this is my first year in operation as a full time day care provider to more than one child. As with any business, the first year is a learning experience. I have learned a lot this year. When I interviewed with some of you, I said that I only take three children. In the past months, I have realized that I am more than capable of comfortably handling more than that. I know that for some of you, this was a selling point. The Ontario Day Nurseries Act dictates that any one home child care provider is entitled to care for up to five children at a time, not including their own.

Having said this, I already know that some of you are not comfortable with my taking on another child, but as with any business, terms and conditions change, leaving clients and business owners with the option of changing with these modifications, or moving on and finding a more suitable arrangement for them.

I do hope that I can keep all of my current clients. Your kids are of great importance to my family and we have true affection for every one. I further hope that you can understand that you must have faith and trust in me, as I am caring for your children. I would never put any of your children in harm's way, and if I thought for a moment that I was unequipped to care for four, I simply would not do it. I now take this opportunity to ask that you please give it a chance before you decide to seek care elsewhere. Your comfort level is valid, but as I have said before, this is my business, and sometimes I must treat it as such, personal feelings and relationships aside.

I will begin to advertise for a fourth child effective immediately. I will, however, push back the start date until one month from now, leaving you the option and ample time to find alternate care arrangements should you feel that it is something that you must do. I would very much like to move forward with all of my clients in place despite this change to my business, but know that I do understand if my new situation no longer meets your family's needs.

With Sincerest Respect,

Alphaghetti
