I don't know if I would let the parent's call the shots. This is your day home and therefore the decision ultimately lies with you. If I were you I would think on it. If you decide to take on the other child then I would change the contract and should they not wish to sign it then I guess they will be looking for another day home. To be honest I agree with the above poster in that I don't really like the parent's attitude either. I would not leave the decision up to them. If its worth it to get another family and perhaps loose this one only you can decide that. You never know you might get a really awesome family out of this. Hope it works out for you whatever you decide!
