A baby had started to cry during the organizational behavior class of lecturer Sydney Engelberg, his daughter, Sarit Fishbaine, told BuzzFeed News.

Fishbaine explained that her dad, a native of South Africa who has taught for 45 years, teaches for the master’s degree program, so he has a lot of older students.

“There’s a lot of young moms and a lot of them have babies, and he encourages them to just bring their babies to class,” she said.
