Otherwise, stick to your rates as you would for any other.
I just told a daycare mom this recently and she looked at me like I was nuts. She is pregnant with twins and asked me for ballpark rates for the 2 babies, all 3 kids together, etc. I gave her the rates but told her I couldn't hold the spots either - when she asked why I don't discount for 3 kids I told her because it is more of a liability to me.
