Harry and Ginny stood in the doorway of their home, dumbfounded.
"Surprise!"
George was the first to be able to wrestle through the pile of blue balloons to embrace the couple.
"I know, I know, but you're the ones that keep insisting on having the brats, so Mum will keep insisting on showering you!"
They grinned as they embraced everyone, before Molly Weasley took their arms.
"Mum, there's really no need for this again ..."
"Nonsense. Now, go upstairs, there's a surprise for you."
It was with trepidation that the couple climbed the stairs, a trail of blue ribbon marking their path.
They stood in the doorway of the nursery, grinning.
"It's very ..."
"Blue," Ginny chuckled.
Harry put his arms around her.
"You can tell her we're having a girl."
