Eleven candles flicker low, In a room where courage starts to show. A birthday with laughter mixed with tears, Amid the trials of precious years. His warrior heart beats strong and true, While winds of challenge gently blew. Immunotherapy’s daunting claim, Turning struggle into a brave domain. Swollen face and an itchy arm, Yet spirits rise, despite alarm. For every shadow has its sun, And every fight that’s bravely won. Beyond the trials lies the day, Where dreams unfold in endless play. So here's to life—this cherished song, To a son so brave, and ever strong.
