Child entertainment star Daniel Coleman, also known as Danny Go, on Friday said his son died after a battle with stage 3 mouth cancer.

The 14-year-old, Isaac, died on Thursday, May 21, Coleman said in an Instagram post made on Friday.

Sharing a picture of his son, Daniel Coleman wrote: "Oh my sweet boy. There’s so much I want to say, but I don’t know how yet. I already miss you so much, and the pain in my heart is far more than I can process. But looking through thousands of pictures and videos this past week, I’m also filled with tremendous pride. 

Your 14 years were full of so many challenges, but you met them all with such grit…and you somehow kept your trademark joy in spite of it all. 

You truly had a spark like no other, Isaac! Remembering how loved you were and how full of life your time here was gives me great comfort. Being your dad was the honor of a lifetime. I’m so proud of you and I love you forever. Rest peacefully, son."
