I think it would be very cost-effective to hire a baby sitter. I get irritated when people bring babies to inappropriate places--concerts, quilt shows, or even restaurants. Nothing takes the edge off a rare night out for me than having to deal with a screaming child or children running in the aisles, etc. Surely adults can figure out how to leave babies at home for a while. A quilt show is such a wonderful experience, I would want it to be a good one.
