are they vegetarian or vegan? there is a dif. and if it becomes too much for you to handle, ask the family to provide all food and snacks. I wouldn't mind having a child that needed special diet, due to lifestyle or religious beliefs, but I would ask for the parents help to provide for the child what the parents desire. def would not turn my normal routine upside down for one child, and would be leary to take a child with any allergies (requiring special diet) due to safety issues, but if the parents were willing to pack the lunch each day and provide a list of what the child can and can't have, no big deal. i did have a parents come to me for care who was raising her child on a no nitrate diet!!!! that was a little extream and I had many concerns, luckily for me it didn't work out. those kids couldn't eat much of anything. felt bad for them.
