"He smiles as he opens them and does his trademark "nose scrunch" to let us know he's happy", said a statement from Jacob's family.
The hospital posted a Facebook update, calling the response "wonderfully overwhelming", and encouraging people to continue sending cards, or to record online videos of their families singing Christmas carols to show to Jacob and other patients. His obsessions include Minecraft and Legos, and he's a huge "Star Wars" fan.
"The overflowing has made my heart full and exceptionally cheerful", said Tara Artinyan, Jacob's stepmother.
Jacob Thompson, a 9-year-old boy with stage 4 high-risk neuroblastoma, loves the holiday season.
Jacob was diagnosed at age 5 with neuroblastoma, a malignant cancer of the nerve cells that is nearly exclusively found in children and extremely hard to treat. "He was excited to see what people had to say and it just brightened his day".
On Nov. 1, Thompson's mother, Michelle Thompson Simard, shared on Facebook that the first card had arrived from a friend named Nolan.
And only five days after he announced his wish, he has already received more than 100 cards from people all over the country - and even beyond. "He's accomplished everything that he needed to do by 9 years old, and a lot of people don't accomplish that, ever".
"We got over a hundred, and they're from all over the world. We have some from the Netherlands, from Australia, from Denmark", Aniyan said.
Since Jacob also loves penguins, the family encourages everyone in a statement to take advice from Jacob's favourite poem; "Advice from a Penguin." .
