“Addy’s symptoms have progressed rapidly over the past day and a half. Yesterday she woke up as her spunky playful self. While we still see short instances of our girl she can no longer eat or swallow without difficulty and she’s sleeping most of the time now and we’ve admitted her into inpatient care. Most likely she doesn’t have much time left,” he wrote on Facebook.

Big brother didn’t want to leave his sister

In an incredibly emotional and heartbreaking post, he invited all those friends and relatives who wanted to say a final farewell to their beloved daughter to contact them.

Just hours after, a post on the Facebook page Hope for Addy Joy – Fighting DIPG, the family announced the passing of their daughter.

“While this is only goodbye for now we miss our baby girl terribly.”

The family donated Addy’s tumors, both brain and spine, to scientific research in “hopes of saving future children from a similar fate.
