Just as parents that are looking for care are not going to find someone that meets everything on their wish list you will need to make a list too. Actually make two lists. Make one that lists what you have now with your families - age, hours, temperments etc. Rank the interviewed families against that list. Make a list of what your ideal would be in terms of what can you not compromise on such as hours, etc. If you can eliminate a family that ends up at the bottom of both lists it will help to narrow down your choices. Again just as a family will always question if they made the best choice no matter how much they love their daycare provider you will always wonder what if.
