I would also choose the older woman even if she's a little out of the way and a bit more expensive. That's really not all that expensive anyway for three long days. I agree with what the other posters said about the other options having their own children. The third option would be my second choice-- just think that someone with two of their own young children in their home may not provide the individual attention your child obviously needs, at least until he overcomes the need to bite others.
