In the Reel, Monroe and her brother could be seen holding hands and walking down the hospital hallway while nurses and doctors cheered around them. Upon returning home, the strong little girl was met with a surprise visit from family and friends holding up pink pom poms and wearing pink cowboy hats and appearances from her favorite princesses Jasmine and Ariel.

Monroe was also surprised with a rainbow balloon arch that read, "Welcome Home," and could be seen posing in front of the display with her brother. Her bedroom was decorated to the nines with balloons, streamers and toys and the family of four enjoyed a rainbow heart-shaped cake that said "MVP" on it — Monroe's nickname from throughout her treatment.

"It’s hard to find the words to fully capture and express the emotions or the meaning of this moment," the proud parents wrote in their caption. "Monroe was dealt a very difficult and undeserving hand in this cancer fight. Her little 4 year old body endured so much pain and toxicity, yet somehow she managed to turned it into a beautiful outcome with her beautiful spirit."

They added that, "Monroe is coming home with lifelong friendships and memories that we will forever cherish."

"Today we begin a new chapter. We will never forget or take for granted the 139 sleeps or days we spent here at Vanderbilt Children's Hospital. Thank you all, and Monroe we are so incredibly proud of you. 🙏🙏❤️❤️," the parents concluded their caption.
