Adrien, then Marinette.

"Alright. Let's change you out of those things and then we can go back to playing."

Marinette gave an "aw" in protest, while Adrien said nothing.

"Alright. You first, baby boy."

While littles weren't usually embarrassed about getting their diaper changed while in their headspace, there was enough of "grown-up Adrien" still there for Adrien's face to blush.

Alya took Adrien by the hand and led him to the changing table. While baby changing tables were chest-high and small, Adrien's changing table was knee-high and almost as big as his queen-sized crib, making it so that he could lie down on it without needing to be picked up first.

Alya undid the tapes of his diaper and got to work.

Changing Adrien that first time was a difficult one for Alya. Not because she hadn't changed a diaper before. She'd changed her little sister's diapers when they were babies and Marinette's diaper a bunch of times before she started taking care of her. But they were girls, so changing a boy's diaper was certainly an experience.

Did you know that baby boys could have erections? They just had them at random. Alya had to actually look up the nuances of changing a boy's diaper and that was one of the first things she learned. Boy-Littles did it too, so wiping him down that first time was rather awkward for everyone. After the first few weeks of baby-sitting him, Alya had grown used to it, and it didn't even happen all that often.

She had replaced the old diaper with a new one, powdered him and taped him up before lifting him into a sitting position. Alya wrapped him in a hug and gave him an exaggerated kiss on the cheek.

"There we go. That better?"

Adrien blushed and nodded with a smile on his face before he laid his head on her shoulder. Something Alya learned with Adrien is that he loved displays of affection. Something she figured was what happens to a little with a cold, emotional-distant father and missing mother.

"Okey dokey. Let's give Marinette a turn."

As Adrien got up and walked off to his toy-chest, Alya helped Marinette out of her shoes and pulled down her pantyhose. She found that Marinette's diaper was soaked to its limits.

"Geeze-louis, Marinette. You were really in need of changing, weren't you?"

Marinette fiddled with her fingers with a guilty look on her face.

"Sowy A'ya. Pee-pee."

"That's alright baby girl. That's what the diaper's for. Now let's get you nice and dry."

She lied down on the changing table, her diaper making a loud squish like a full-sponge, and Alya changed her.

When it came to changing Marinette, Alya was a pro. She had been changing her since the beginning of school. Sometimes Marinette would have an accident while out of her headspace -- which wasn't uncommon for littles -- and Alya wouldn't hesitate to help. Alya had taken to experimenting with diapers to see what looked the cutest on her baby girl.
