I do not hold spots and in this situation I would not hold it for this mom either. I would tell her that she will be put on your waiting list and if the spot is still available when she needs it that you will contact her then. I have someone interested in my spot that is open next week. I don't have my paperwork back signed or my deposit cheque yet so I have another meeting set up for tonight. If tonight's interview is a good fit as well and is willing to pay starting next week and have cheque in hand then the other family will be SOL. I do not take a cut in wage for anyone.
