Harry Styles/Louis Tomlinson, 24,590 words, Explicit, written for onedirectionbigbang
Louis turns into a three-year-old - literally. He's his normal self for anything they really need him to do, like shows and interviews, but the rest of the time he's a toddler. The week Harry spends taking care of him gives them a chance to be close again, and to figure out that they want to be even closer when Louis's back to his normal adult self.

There's a little kid in Louis's room. He's sitting on the floor in the shirt Louis was wearing earlier, which is far too big for him, and he's holding Louis's phone, which is also too big for him.Read it on AO3
"Harry!" The kid smiles, and Harry knows that smile. "Mummy, Harry's here. And Paul," he adds with a pout Harry also knows.
The phone's on speaker; Harry and Paul can clearly hear Jay say, "That's good, darling. They're going to look after you."
Harry feels a bit faint. Louis might somehow manage to prank them like this, but there's no way he would be able to get Jay in on it.
"Can I talk to Harry now?" Jay asks.
The kid - Louis, because it has to be Louis - toddles over to Harry and holds the phone up to him. "Mummy wants to talk to you."
Harry crouches down to take the phone from him, because if he can't resist little kids, he certainly can't resist Louis as a little kid. "Thanks, love."
Louis beams at him.
