The couple are planning to call their first born son Jayce.
"It's come along quickly," Wilson said after they posed for a picture shoot.
"The photos look great, but it's so surreal. I remember a couple of the older boys at the Giants got a few done and I was like, 'Gee, I can't wait for myself to be in that position at some stage'.
"Hopefully he arrives safely and is ready to kick a footy around."
Unfortunately, the unique selection of ensembles for the photo shoot have attracted criticism from fans online, who have labelled the series of photos "cringe central".
It's certainly got people talking.
Readers on The West Australian's Facebook page were less understanding.
"One of the most unnecessary page 3 pics ever," one reader commented.
"Why would you make us see that?! It's a horrible pic (what is she wearing? Undies?) I have no idea who he is but if I did, I'd still wonder why the p3 was assigned to this?!!!"
Another reader wrote: "How weird was that page 3 pic. Cringe central".
Wilson grew up in Mandurah and even played for Peel Thunder before being picked up by GWS as an underage selection before making his AFL debut in 2012.
He was earlier this week handed his first Freo jumper with the No. 14 on the back.
He was presented his jumper by Freo life member Antoni Grover.
"When I got drafted, I was a natural forward and I went into the backline so, hopefully, Antoni can give me some good tips for the next couple years," Wilson told the Dockers' website.
"I grew up going for Freo and he was one of the stars, so I'm grateful to get the number 14."
