The only thing I would do during the interview for my own comfort would be to request she have a lot of floor play, keep an eye on her behavior as far as putting things in her mouth. That could be real scarey if she has a habit of putting things in her mouth as so many do at that age, with severe allergies and those habits you could have a lot of stress on your hands if you take her. Nothing wrong with having a child with allergies, just be aware of the stress and liability that can come with it. Sometimes the spot filled and the paycheck can't outweigh the issues that can come. Make sure the parents are open and honest regarding any and all concerns. Does any one ever have a seperate contract regarding such things as allergies and other medical needs for the children, for further protection of the provider given a medical emergency arises? just a few thoughts I would have.
