Oliver William Hartfield, 15 months, peacefully passed away on Friday, April 26th, 2024, in St. Petersburg, FL in his mother’s arms surrounded by family after a long and complex medical journey.

Oliver was born December 30th, 2022, to parents William and Kylie Hartfield.  Oliver was born in St. Petersburg Florida and was immediately admitted to Johns Hopkins All Children’s Hospital to receive specialized care for congenital diaphragmatic hernia. Oliver weighed just 2 pounds and 14 oz at birth.

It was discovered that he also had esophageal atresia tracheal fistula and several heart defects. All these abnormalities required multiple surgeries, which Oliver conquered one by one. He beat all odds and was thriving. Oliver was discharged from Johns Hopkins All Children’s Hospital in September of 2023.  A few weeks later he was able to go home to Mesa, Arizona where he had the best five months of his life experiencing life as a “normal baby”. In February of 2024, Oliver returned to Florida to have his last needed surgeries and was recovering well.  However, a few weeks later Oliver unexpectedly experienced cardiac arrest which left him with a brain injury that only worsened over time.

Oliver was a strong, resilient, happy, and feisty little red headed boy that was loved by everyone that met him. Even those that never had the opportunity to meet him knew how special he was. Oliver loved to play with his toys and to explore around him. His favorite toy was the “O ball” or “Ollie ball”. This ball was a comfort to him from a very young age.  Oliver loved play time with his mom and dad and kept them very busy at home.  He also loved watching mickey mouse clubhouse, which was especially comforting to him when he was in the hospital.  Oliver brought so much joy to everyone around him.

He is greatly missed by his parents, family, nurses, and doctors.

Oliver is survived by his loving parents, grandparents, aunts, uncles, and cousins.

A special thank you to all those at John Hopkins All Children’s Hospital that gave Oliver the very best of care. You are like family, and we are forever grateful for each one of you.

    It was always a joy to see your updates on facebook of your son. We only knew each other in college, but I remember your posts vividly. As a mother of two who posts quite a bit of my own children, I liked seeing the posts of your adorable son. His fight was an incredible journey that I know will stay with you and strengthen you. I often find it unfair that some children have so many tough struggles here on Earth. He was a fighter. None of it was in vain. You can be sure that he will be doing a wonderful work with his Savior. Your child will always be with you. Every kiss, squeeze, handhold, giggle, and hug you gave your precious angel were worth it. Those memories will warm your heart on the dark days.
    Condolences and prayers to your sweet family. May you find comfort in the eternal plan. ❤️

  • May God give you comfort and strength at this time. We are sorry for the loss of your child. We are praying for you and are in our thoughts.
