Well in this case, there is only one option left. Ask his father(your husband) to look after his son, simple. You don't pay for the days you use you pay for the spot. As I've said before your day home provider depends on her business and the income she is getting from it. We are all connected to each other somehow.

I keep low ratio(3kids only) and I do charge them a bit more then the day homes in my area. And last month one of my families gave me notice after starting with me previous month. So just after a month of them being here they gave me notice because their single parent friend has decided to open a day home and they are helping her. I wish they told me that it will be only for a month so that I wouldn't let other interested family go. Now, a big chunk of my income has gone. I was thinking "what if I have to pay mortgage, what if I have commitments? I would be doomed! We are thinking of buying a house but I can not relay on my income. What your day home provider doing is protecting her business and her income which you and your husband should understand. And if you don't want to pay I'm sure you can find a stay at home mom who is willing to take your son or someone looking to do this until they land on to a better! Paying job. So be prepared.
