My father in law was diagnosed with pancreatic cancer when our first daughter was 9 months old.
That's so sad. I'm sorry to hear that. Is he getting a treament? 
He passed away 9 months after diagnosis, when she was 18 months old.  She just turned 18 this year, so it's been awhile.  But he never really got to know her and never met our 2nd daughter at all.
Wow, that's awful. I hope you can tell her all about him and share some pictures at least.
