Miruhawks
SPOILER FOR CHAPTER 262

Dove was obviously born after the war arc. She didn't know how bad it was and got really curious about her mom not having an arm and sometimes having an arm. So she asked during a tea party and both her parents were tryna figure out how to tell her what had happened and Dove is sitting there like 0-0-

Iidamei

Tameiko has tea parties with stuffed animals or none at all.

Kamijirou

"Mmm, this is a very fine tea Stormi. Don't you think so Riitsu?"

"I hate tea"

"Denki don't make him lie."

"Daddy, do you like the tea?"

"No."

Dabi x Toga

They don't have tea parties but Dabi plays with his quirk. Like, while their son was a baby, he'd ignite his hand, when his son reached for it, he'd close his hand, making the baby laugh. Toga and him play games like peekaboo while she was a baby.

Nejitama

Amai is busy fighting a kid, Pheonix has tea parties though. Tamaki loves playing with his son, Nejire tries but she gets kinda bored, then she has to help some random girl Amai fought.

Mt.Kamui

Kamui and Okūri are besties when it comes to tea parties. When they don't have tea parties, Yuu and Okūri are besties.

Ryushot

I dare that kid to mess up their tea. Like, I dare her.

Megami had them when she was younger and Shinya was holding back all of his criticism because she was pure. Ryuko fakes drinking it and pours it onto a plant. The plant dies.

Daenerys is good at making tea and Shinya praises her. Megami gets jealous because he never said her tea was good. It's the only time Daenerys actually feels like she gets more attention than Meg. (Meg is extra and needs more attention or else.)

Reiko x Shinsou

Rosalind gets excited when her dad decides to join. She makes them dress up and does her mommy's hair (ties the Big Bang back so both eyes are visible) and wears her nicest outfit (a formal dress, a feather boa, and sunglasses) and they have a serious tea party. Shinsou finds it hilarious cuz she made the chinchilla and cat participate too.
