I'm so sorry, but I'm with Macca. I actually did an awful thing to a classmate two years back. Her CC options had fallen through last minute, and she got special permission to bring the baby in with her. Her having the baby wasn't the issue - it was everyone else who would hold her and not leave the room if she started to cry.
I ended up making a formal complaint, because I found it distracting, and I don't have great hearing so I was missing out. The mother concerned was asked to leave and a study from home package was developed for her.
All of her friends then went on the witch-hunt to find out who it was, and I had to lie to them. It was awful. I felt so bad, but I was paying for the study just like she was, and I felt that it was unfair.

So please, please from a fellow student's point of view, don't do it!
