Most babies love to smile and cuddle and play, but Felicity is one of the happiest babies you’ll ever meet. She's special, and her name matches her personality to a T.
Medically, she’s nearly unique.
“We went to our pediatrician for her four-month checkup,” recalled her mother, Mandy. “Being a first-time mommy, I was so scared about getting her shots.”

But the family was in for something much scarier.
Felicity’s pediatrician suspected she might have a condition that causes fluid build up inside the brain — known as hydrocephalus — and ordered an ultrasound, which led to a CT scan, which led to a stay in the pediatric intensive care unit.
Felicity's family was given the news that a giant cyst was pushing Felicity’s brain aside, essentially mashing it into her skull.
And this still wasn’t the worst news.
Felicity had a total of five brain and spinal tumors called desmoplastic infantile astrocytoma: not cancer, but aggressive and deadly all the same.
The family sought a referral to St. Jude Children’s Research Hospital and arrived on Father’s Day 2017.
Her diagnosis is immensely rare.
Her doctor said he's never treated a case like hers ever at St. Jude, and neither has any other doctor.

But St. Jude is leading the way the world understands, treats and defeats childhood cancer and other life-threatening diseases. Felicity’s doctors quickly came up with a plan.
Felicity received several different chemotherapies that succeeded in shrinking her tumors. She also received supportive care, like physical, occupational and speech therapies, and lots and lots of love.
Her parents have been able to take their happy baby home, but St. Jude continues to monitor her closely, and she returns often for checkups and scans.

Felicity almost shares a birthday with St. Jude founder Danny Thomas.
While she was in treatment, clinic staff celebrated her first birthday on the same day they commemorated Danny Thomas’s birth (Jan. 6), to her family’s delight.

St. Jude is ... well, it's become our second home. It's the best thing that could have happened to us in this situation. If we had chosen not to come here, I don't feel Felicity would be with us today. I don't even have the words to say what I want to say, because it makes me teary-eyed.
