“During those first 8 or so weeks I was so sick I couldn’t even walk to the bathroom without feeling as though I was seconds away from throwing up,” she explains in an exclusive chat.
“The first trimester tested me big time! I was eating whatever I could simply to survive the nausea!”
Speaking of her very relatable cravings Elyse confessed it came down to “bread, pasta and chicken rolls.”
Block winners Elyse and Josh first met in Byron Bay, NSW in 2013 before they competed on the hit reno reality show together in 2017.
The couple announced their exciting baby news to fans and followers on Monday, revealing that their little one was born a four days before.
“The next chapter in our lives. The best chapter yet,” Elyse captioned her post of her newborn's tiny feet.
