I always thought it would be cute if Harry & his wife had two twin sons who were about 2 years old and a newborn son and the twins would always tease the newest member of the family by dangling pieces of food in his face or throwing his toys around and the newborn would at first giggle, but then get frustrated and start fussing a bit and H would gently scold the twins saying that they have to be nicer to him :')
Ohhhh my goodness.
And Harry picks up the fussy one and shakes his head at the twins, putting on his best stern dad™ face. “Boys, y'cant keep doing this to him. S'not nice. You wouldn’t like it if I did that to you.”
“Yeah but we’re just having fun!” One of the older boys would lisp, and Harry would shake his head again.
“S'not very fun, bud. Not for anyone else. You’ve gotta think about his feelings. He doesn’t understand things the way you two do. You’ve gotta be good big brothers and show him the ropes.”
“But we tease each other all the time!” The other twin speaks up. “That’s what brothers do!”
Harry sighs. “Well yeah but that’s because you guys are big boys. Your brother is still learning. When he’s bigger you can play with him all y'want. But right now, you aren’t being very nice big brothers.”
The twins frown, as if that was the worst insult they could ever receive. Both recite a quiet “sorry daddy” and Harry smiles.
“Hey. Everything’s okay. It isn’t me you should be sayin’ sorry to though.”
The twins take turns kissing the fussy baby’s head and saying sorry. “HERE!” One of them says suddenly, running over to pick up the toy that they’d thrown the room. “You want this?!”
