“The Daddy Switch”

https://archiveofourown.org/works/88534306 by Izzi658 Tony Stark can teach chemistry to a room full of teenagers. How hard can one tiny baby be? Very hard, it turns out. When finances force Steve back to work and Tony into the stay-at-home dad role, Tony is confident he’s got this. He’s a genius. He’s charming. What could possibly go wrong? Everything. Everything goes wrong. Sleep is a myth. Showering is a luxury. His only clean shirt now has a mysterious stain. His only adult conversation is with a two-month-old who just blinks at him like he’s an idiot. Meanwhile, Steve is back at work, hitting the gym, and completely oblivious that his husband is one diaper blowout away from losing it. Tony has a plan: fake it ‘til he makes it. No way is he admitting defeat. But between the 3 AM feedings, the isolation, and the growing resentment he refuses to acknowledge, it’s only a matter of time before his carefully constructed facade comes crashing down. A rom-com about role reversal, postpartum bodies , sleep deprivation, and learning that marriage means showing the messy parts—even when you’d rather pretend you’ve got it all together.
