You make a great point, just wanted to point out that traditionally the name is "booth babe" (as opposed to baby, which largely fell out of favor after the Austin Powers movies). I learned about this term from a female employee who also happened to be an excellent coder and a victim of statistics.

Not that I wouldn't like to see a booth baby - a toddler with a mini Python shirt would be adorable and would certainly drive more traffic to your booth.
