Facebook founder Mark Zuckerberg welcomed his first child, a baby girl named Maxima, earlier this week, and he's celebrating in a pretty unconventional way.

Forget 'wetting the baby's head' with a few pints or sending around a family photo – instead, Mark's giving away a fairly large chunk of his income.

Practically all of it, to be frank. Yes, Mark and his wife Priscilla have pledged 99% of their Facebook shares (approx. €42.4billion) to charitable initiatives, to help create a better world for little Max and "all children."

The entrepreneur announced the news – and his daughter's birth – with a Facebook post last night.

"Priscilla and I are so happy to welcome our daughter Max into this world!" he wrote alongside a family photo.

"For her birth, we wrote a letter to her about the world we hope she grows up in….We are committed to doing our small part to help create this world for all children.

"We will give 99% of our Facebook shares during our lives to join many others in improving this world for the next generation."

Unsurprisingly Mark's wide-reaching statement has already come under some scrutiny, with critics of the plan pointing out there are many loopholes for Mark and Priscilla.

The money will be shared through a company, the Chan Zuckerberg Initiative, rather than a charity, meaning it "will be able to spend its money on whatever it wants, including private, profit-generating investment," according to Gawker.

Right now though, the real question for us is… can baby Maxima ever beat Mark and Priscilla's dog Beast in the cuteness stakes?

We think not.
