Thompson, also mom to 2-year-old Waylon, said Bella visits Cypress Regional Hospital in Swift Current monthly to receive infusion therapy for her SCID.

On Jan. 29, Thompson shared a video on TikTok of Bella dancing to a song from the popular kids' film \"Trolls.\" The footage garnered 4 million views, and Thompson said she received many heartfelt messages and well wishes for Bella.

\"A lot of adults are like, 'If I have a bad day, I'm stressed out' or 'I'm going through a similar medical scenario and Bella gives me a joy,'\" Thompson said. \"It's exactly what I hoped for -- to give people a sense of hope.\"

Dr. Billie Au is a clinical geneticist at Alberta Children's Hospital who's worked with Bella.

Au told \"GMA\" that Bella having the three conditions is rare, though they're all due to the same genetic cause.

\"Cognitively, she's a very smart kid,\" Au said. \"She goes to school. None of this affects her brain at all. I've always been really impressed at how Isabella and her family [are] happy and adjusted ... despite of what she's had to go through.\"
