Miguel Cervantes -- star of Chicago production of Hamilton -- shared the heartbreaking news that their three-year-old daughter, Adelaide, passed away.

Adelaide Grace Cervantes died Saturday, October 12th, just a few short days before her fourth birthday. She succumbed after battling Infantile Spasms (IS) and epilepsy, a condition she had since she was a baby.

Miguel and his wife, Kelly, posted a black and white photo of their daughter's room on Instagram on Monday to share the heartbreaking news:

The machines are off. Her bed is empty. The quiet is deafening. Adelaide left us early Saturday. She went peacefully in her mother's arms, surrounded by love. Finally, she is free from pain + seizures but leaves our hearts shattered. We love you so much Adelaideybug and forever after  

In a statement to People Magazine, a representative of the family said that they are heartbroken to announce that their baby girl passed away early Saturday morning. They also extended their sincerest, heartfelt gratitude to all who have reached out with words of support and prayer, and that they will continue to feel the love as they go through this difficult time.

Adelaide suffered her first seizure when she was only seven months old. Two months later, she was diagnosed with IS -- resulting to several seizures in a short time. In 2018, Miguel and Kelly said in an interview that Adelaide missed a lot of the traditional milestones of being a baby.

The couple, who also have a seven-year-old son, Jackson, transferred Adelaide to hospice care in August after discovering her condition was neuro-degenerative and that her brain had shrunk in size.

The family was even able to keep their daughter at home during her final weeks.

Kelly's popular blog, "Inchstones," has been an outlet for her. She recorded Adelaide's story in her blog through the years.

Moreover, through her work with the Citizens United for Research in Epilepsy (CURE), she was able to help raise funds for the research that aims to find a cure for the devastating illness.

In a blog post addressed to her daughter after being transferred to hospice care, Kelly admitted that her daughter would not get better in time. Moreover, she knows the skills Adelaide learned will soon be lost and not be regained. The mother of two addressed Adelaide and apologized for the way her daughter's body betrayed her.

One day before Adelaide's death, Kelly described her baby as a warrior and the most energetic person she has ever met. She believes that Adelaide came into the world and had a mission and a story.

Meanwhile, Jackson served as endless bright energy for his sister and the family. Kelly said Jackson keeps him strong.

On Sunday, the actor confirmed that he would briefly take a break from his leading role in Hamilton.
