I think you should be relieved!!!
I am all for same sex partnerships, and healthy lifestyles... good for her. But she threw out sooooo many other warning signs. Padding, really????? It's a humorous mental picture, but in practice, I really do feel bad for this kid.
It's one thing for someone to say "I want to make sure that this transition is easiest on everyone, blah blah blah". It's another completely to barge in and expect that all of your demands will be met, no questions asked. She sounds like a horribly abrasive personality. Gee, I wonder why she doesn't do daycare herself anymore? Probably chased everyone off!!
By the way; when you first explained it, I was wondering if it was someone trying to do sneaky spying for thier own daycare. I mean, staying all day, every day for a MONTH??? Seems really fishy to me....
