I was a grad student at Brigham Young University, which has a very high marriage rate, and a large number of grad students (if not most) were parents.
A couple of different parents brought their newborn child to class for a semester (an undergraduate class once and a graduate class the other time).
Some people felt uncomfortable or distracted by the child. I thought the parents did a great job, and soothed the child whenever it was fussy.
After a few semesters that it happened, teachers started putting 'No babies allowed in the classroom' on the syllabus.
Many of these parents had only one semester left, and had no access to childcare for such a young infant.
How should this have been handled to everyone's satisfaction? If babies were not allowed, how and when should this have been communicated to the parents?
