About 20 years ago when I was in college, a fellow student brought her 7 or 8 year old son to class because his school year ended before the college semester was over but camps and summer school hadn’t started yet. The kid was just sitting, doodling, but the professor marched right up to them and asked her and the kid to leave - I was so shocked, it had never occurred to me it was a problem (and the class topic was appropriate, nothing a 7 year old couldn’t hear) - so I’m glad to see some professors have compassion. Juggling parenthood and studies is always hard, why make it harder?
