How to Dad reveals big baby news

How to Dad, New Zealand's favourite vlogging father, has taken to Facebook to share with his followers that he and "How to Mum" are expecting baby number three.

The video, titled How to tell people you're having a baby begins with How to Dad, Jordan Watson, explaining that the first rule of making such an announcement is to not put it on Facebook becuase "it's already full of people posting baby stuff and then your friends end up blocking other friends because of too much baby stuff.

"So number one rule, don't put it on Facebook."

And in what was almost a first time reveal, How to Dad invites How to Mum into the video as he states they "officially do not have another baby due later this year."

But How to Mum only partially steps into the frame, enough to high five How to Dad, before exiting the video.

Viewed 177, 000 times, the clip also features Watson's two daughters who don't quite manage to keep up the charade about "not" having another baby on the way.

As How to Dad asks, "Do we have another baby on the way?" the girls excitedly scream "Yeah!"

After sharing the video, How to Dad urged his followers to stick with him, commenting "Don't block us ay."

One follower suggested that his next video might be titled "How to not p**s a pregnant wife off."
