Mark Zuckerberg has posted photos of him changing his daughter Max's nappies on Facebook.
The Facebook owner posted the pictures to his Facebook page, with the caption "One more down, thousands to go."
Officially making him a cliche dad.
The post was a part of his recent update in a long series of posts about his two months paternity leave.
He also posted photos of his wife and Max sitting with him as he reads his newborn a "Quantum Physics for Babies" book.
Most Facebook users took to complimenting Mr Zuckerberg and his family, however one Facebook user added:
"I'm geeky but I actually did calculate the rough number of diapers; I thought thousands might have been hyperbolic, but it's not -- that's the right order of magnitude."
