Jamie-Lynn Sigler and her family are  YearOldSonBeauHospitalizedforDaysAmid NightmareIllness Cassian Grantcelebrating after a terrifying ordeal.

The 43-year-old actress previously revealed that her 10-year-old son Beau was battling a “nightmare” illness that doctors believed to be ADEM (acute disseminated encephalomyelitis).

“To say this has been hard, is an understatement, and I’ve never felt more broken,” Sigler, who also shares son Jack, 6, with her husband, Cutter Dykstra, wrote in an Aug. 6 Instagram post. “But, I have also never felt more love. The way our friends and family have come to our rescue during this terrible time has been one of the most incredible things to experience.”

ADEM is a rare kind of inflammation that affects the brain and spinal cord, according to WebMD, and can be treated.

As Sigler shared of Beau’s prognosis, “We have the highest of hopes for our son that he makes a full recovery.”

And in a touching video on Aug. 16, Beau proudly danced his way out of the hospital as the nurses and staff cheered him on.

“After 33 days, we are busting out of here!” Sigler captioned the Instagram video. “My brave boy, you are a walking miracle. The rest of this story will be Beau’s to tell, if he chooses to one day.”

The Sopranos star, who previously disclosed that she has been battling multiple sclerosis since the age of 20, praised the staff of the Dells Children’s Hospital, writing, “I’m in awe of your patience, dedication, and expertise…. But, no offense.. I hope we never see you again.”

It’s been a traumatic time for Sigler and her family when it comes to their health.  In June, Sigler shared that she had a near-fatal surgery in 2023.

"I had a very bad reaction to a surgery and got sepsis and was in the hospital and almost died,” she explained on her MeSsy podcast, which was recorded earlier in 2024. “I had never in my life been more sad. Felt more low.”

Sigler added of her journey with MS, "It's so hard to live in a disabled body. But what makes it harder is when you compare it to how it used to be."
