I have been open less than 6 months, and would like to shut my doors in the fall. Daycare isn't a great fit for me or my family it turns out after all. I feel quite guilty (and slightly embarrassed) but I just tell myself that I've done the best that I can and have realized my limits.

I only have ONE child part-time. While his parents are lovely and very supportive of working together, he has been incredibly challenging (food issues, constant crying, clingy, doen't socialize well, etc). I have been so stressed out and frustrated all these months caring for him. My decision to close my doors was solidified by the fact that I've noticed he's affecting my children's happiness. My daughter tells people "we do daycare and all (child) does is cry"

His schedule is changing too which is another factor. His parents didn't mention it at the interview. I don't, and probably won't in the long term, be able to accommodate it.

A friend passed along a job posting in my field so I went for an interview. I got an email today letting me know I got the job. It will essentially replace the income from doing daycare.

I have questions related to terminating.

(1) Do I give the parents a letter cold turkey, email, or do I call them to let them know what is happening? I will of course be giving them an official termination letter but just wondering how this is best handled.

(2) Do I give them reasons?
I know I'm not required to professionally. I struggle with this because they are such a nice family and will be disappointed (probably upset and maybe a little angry?) because they have really made it known to me how much they appreciate the care I give their son. Do I tell them I find their son challenging and have realized he's not a good fit long term? Do I tell them the change in schedule won't work? Do I just say I found a job in my field and leave it at that? Or, do I mention all the reasons?

Thanks for reading, and I would appreciate any advice you may have to offer
