Having twins is joyous, stressful, and hectic all at once.
Sadly, none of my married siblings have had twins (yet) but I've heard from all my friends that they really do bring double the joy to their families.
Erica Newschafer already knew what to expect when her twins were born - because she had given birth to another set of twins just four years earlier.
But loving dad Weston filmed every moment of her labor, and managed to capture a heartwarming moment.
As the Newschafers share on their blog, Twins Twice, they had already welcomed a daughter, Mylee, and a pair of twins, Kai and Mia, by 2013.
Then, Erica learned she was pregnant with twins again, and had to start planning for another grueling delivery.
At least, that's what she was expecting.
In fact Erica's labor (her second natural birth) lasted just three hours, which must make mothers everywhere extremely jealous.
To capture the whole event, Weston arrived at the hospital with his computer, iPad, and GoPro camera ready.
While the full video is funny and sweet, the moment that really drew a reaction came at the very end.
Even the nurses were stunned
Is it possible to see so many births that you become jaded, and stop appreciating the wonder?
Maybe, but the nurses who helped Erica during her delivery obviously have not reached that point.
They gasped and covered their mouths as they heard the sound of Erica's babies crying.
This time the Newschafer's had waited until the delivery to learn their baby's genders, and they were pleasantly surprised by two healthy boys.
The video of the birth, which has been viewed more than 2 million times, seems to have something for everyone.
Some commentors liked Weston's goofy jokes, while others congratulated Erica on the speedy and safe delivery.
As another mother's birth story proves, giving birth isn't always so easy...
