Thanks for all the great help!

Here's what I've come up with:

Dear XXXX and XXXX,

After careful consideration and reflection, it has become evident that XXXXXXXXX Dayhome is no longer a good match for XXXX's needs. Due to XXXX's ongoing behavioral and attitude issues, I will no longer be able to provide childcare for her effective XXXX. In addition to these behavioral issues, I find XXXX has a complete lack of respect for myself, my rules, the other children in my care and my facility. I also find that my illness policy has not always been fully respected, which has contributed to making caring for XXXX very difficult at times.

I wish XXXX the very best in the future.

Sincerely,

Me

Sound alright?
