If the agency isn't able to provide you with older kids then maybe now is the time to consider leaving the agency in the sense that if there are calls for private then having even one more under 2 gives you more income than now - even having two under two would give you more income than now since the agency wouldnt' be skimming. Take that dab extra in income and set it aside for a downpayment on a house. Even a townhouse assuming the complex has no restrictions tends to attract the families in the same complex or at minimum attract more than a condo/apartment does.
