Feeling bad about a daycare letter.

[SillyGirl_C]

I think some of the comments above are maybe a little harsh. Daycaremomm was being genuine in her question.
Kids and care are personal, business is not. So the clash in the daycare world can be particularity stark and jarring. Your provider sounds top notch and if your child is happy and well cared for, she is on her A Game.
The paperwork is only a formality and one needed to ensure communication is clear. It seems harsh, but it is really just to document the facts and make sure there is no communication issues, and is not a reflection of her feelings about you or your kiddo. With the quick hi/byes at the door, she is just ensuring she is available to the other kids and keeps the day rolling.
I think you choose well and should take the letter as proof that you have hired a very professional and well trained care provider.
That said, if you think that the part time hours are causing issues with her schedule (see Mickyc above) just ask her if everything is all right? A good face to face conversation clears the air and will give clarity to both you and her.
