I don't offer sibling discounts either. Here on the East Coast, I have just put my prices up to $35 a day and that's too high for many, many. Care can be found for about $30 in this area and of course, there's always the work under the table day carers who will do it for even less - with food.

It's not often I am asked for a sibling discount but I am not financially responsible to support a strangers family due to their money situation, which is effectively what the request for a sibling discount is. It's removing my income, to make their expenses more manageable.
