Louis and Harry are parents to Darcy, Holly and Jamie
This is different family members getting sick.
Liam is Harry's brother and has a wife and one child.
Zayn is Liam and Harry's father and the kids grandkids.
This is a story me and Noorie9 have been working on together.
It is about Liam having a severe stomach bug, and eventually passes round to the others.
It is a bit goory in places.
