How long does it take for a baby to be born in Fallout Shelter?
3 hours, no more no less. Then another 3 hours for them to grow up. It's like waiting for a pizza, but longer and with more responsibilities afterwards.

In Fallout Shelter, expecting a little Vault dweller takes exactly 3 hours of real time. Once the baby making process, *ahem*, concludes, your dwellers will have to wait around 3 hours before the baby is born. After that, it takes another 3 hours for the baby to grow up and start contributing to the vault. So, grab a Nuka-Cola and chill, because you've got some waiting to do!
Honestly, it feels like forever when you're excited to see your vault grow. But yeah, 3 hours till birth and another 3 to adulthood. Makes you wish you could speed up time, doesn't it?
