Yes... too wordy.
2nd draft.
It is not your responsibility to tell the client what type of daycare the child will benefit from. Never admit that you can't handle the child " more one on one time then I can provide "
You have done nothing wrong.
Basic and simple... If you want to elaborate in person then that's great. But the letter should say just basically...
Due to Sam's aggressive behaviours, I will no longer be able to offer care for him. His last day of care will be November 5th 2013.
I am happy to offer you 2 weeks of care in order for you to find alternate arrangements, however, payment for the 2 weeks will need to be made in advance.
I wish you all the best in finding the right fit for you and your family.
Sincerely....
When you hand the parent the letter let them know, unfortunately you won't be able to care for him anymore. You are not able to watch him every second and he has shown behaviours that worry you when it comes to the other kids.
Don't mention school or what you think would help him. It's just factual. " This is why I can't, I wish you the best of luck finding someone who can."
Parents can get very defensive and you don't want the parent to be defensive when reading the letter. "well, she has no right to tell me what my child needs.... She doesn't know what goes on at my childs school" The parent will miss the point. The point is, the child is no longer welcome in your home.
Yes, we all needs to grow a set of balls on days like this. It absolutely sucks! But being taken advantage of, having another child injured in your care, getting stiffed for 2 weeks of pay... these are all things that suck more.
Good luck. It will all be over soon.
