I don't have much advice, but wanted to say that I hope that you find a good place - and they are out there.
The daycare that I worked at completely stopped serving all apple products in all rooms while I worked there. Granted, this was after I got picked up by an ambulance, but they asked if I needed it before, and I had told them no, so it was my fault - I didn't think that I was so sensitive. There are good places and people out there - I wish you luck in finding one.
