Hamish Blake celebrates his first Father's Day in the best way possible.

2014 is the first year that Hamish Blake has been able to celebrate Father’s Day. His son – appropriately named Sonny – is now three months old and quickly proving his existence as the cutest baby in at least Australia, if not the entire world.

Hamish’s wife, Zoe Foster-Blake, posted her tribute to her baby daddy this morning with the below heart-melting Instagram photo:

With the caption: “Sonny doesn’t have a CLUE how lucky he is to have such an incredible dad yet. But he will. And he does. And I’m one grateful son of a squid.”

And Hamish responded with his own, equally gorgeous Instagram photo, thanking his “tiny man and his brilliant mum”:

The full caption: “Special shout out to this tiny man and his brilliant mum. Without them I would not be able to drive down the street on my gold spray painted ride on lawn mower today playing saxophone as part of the Dad Parade I have organised in my street (but haven’t told my neighbours about).”

If you, like us, are tempted to steal this baby, please resist those urges and flick through the below gallery of his beautiful face instead.
