The others have this theory that Tony Stark didn't actually make his money by designing weapons. No, they're pretty sure he made it winning bets because he has yet to lose one. In my headcanon for this universe, he'll narrowly beat Betty at the baby pool, by wagering on a little girl, born six days early. And Clint will win a private wager with Natasha when Tony hands over a tiny onesie that's stain-proof, temperature controlled, bullet-proof, wind-proof, and printed with baby-fied Black Widow symbols in Hawkeye purple the day Evenelle Katerina Barton is born. The suit is adjustable, too, newborn to 6mo.

Natasha foolishly thought he'd wait at least a week.

Baby angst can be fun to read, but I'm afraid I'd be terrible at writing it. And I knew you liked babyfic, so I went about it the only way I could: with lots and lots of alien jokes. And a magic fountain. Cue the horror fic sequel when Natasha realizes that thanks to the Fountain of Antigua, she will soon be getting her period for the first time ever....

And...Sretan Božić!! (I hope I got that right)
