Anyone knowing about dramione pairing fanfiction where there is ministry law in 8th year Hogwarts , there have been given 1 dorm where 2 rooms are given initially. Later 1 room is for them and second for baby. There are sessions to get to know each other. They have been given a magical baby in order to learn parenting for initial days which will disappear later.
This? It's an old story but it does have them in their own dorm and a child that dissapears:
Future Parents Program By: Avari20 - T 15 Chapters - AU 7th year…This was not Draco’s day. Hermione unceremoniously shoved something under his nose. It was a doll.“Draco Malfoy, meet your child.” “Doesn’t look a thing like me,” he told her. “Been seeing the milkman behind my back, Granger?”
