"In the future, if you are having trouble finding someone to watch Korbyn, please feel free to just BRING HER with you to class. I would be absolutely delighted to hold her while I teach, so that you can still pay attention to the class and take notes.
"I work for the Department of CHILD and FAMILY Studies... so how terrible would it be, if I was unwilling to have a child visit out class? I'm very serious with this offer... just bring Korbyn with you!
"And your absence from class today is considered 'excused'."
King took to Twitter to share her professor's email, writing: "Told my professor I missed class yesterday because I couldn't find childcare & this was her response. I'm literally crying. So blessed/thankful".
Her tweet has since gone viral, receiving more than 26,000 likes and 5000 retweets with social media praising the professor.
Even University of Tennessee chancellor Beverly Davenport retweeted King's post.
"Morgan, thanks for showing us challenges college students face. Prof Hunter, thanks for being part of the solution," Davenport wrote.
King is a single mother who lost her own mother to breast cancer last year.
She said balancing school, work and motherhood by herself can be tough, but told Knox News she will continue to push through the barriers.
"It is so hard. But I am so determined to graduate and get my degree for Korbyn and I.
It's not just about me anymore. I have to do this for us."
