Amanda Osbon studies at DeVry University, located in south Nashville, and didn't have a choice but to take her son to class on Monday.
She told WKRN-TV her son, who is almost 2 years old, got up during class and wanted to be held by the professor.
Professor Joel Bunkowske, who Osbon says "was amazing, patient and kind," didn't skip a beat.
He picked up little Xzavier and continued to teach his class.
"Most of us in the class are parents, so everyone was very understanding that he was there," Osbon wrote..
She admitted it was embarrassing at first until Professor Bunkowske noted that everyone struggles, and that's OK.
