Elyse Knowles shows off her slender post-baby body in a bikini as she hits the beach

Elyse Knowles and her fiancé Josh Barker welcomed their first child together, a baby boy named Sunny, back in February.

And on Sunday, the 28-year-old model and her fiancé enjoyed a family outing with their baby boy in Byron Bay.

Elyse showed off her slender post-baby body in a bikini and skirt as she enjoyed a beach day.

The former Block star teamed her ensemble with a mini skirt and a white cap as she enjoyed a stroll on the shore.

Elyse wore sunglasses and held a white bag as she walked alongside her fiancé Josh.

Josh dressed casually in shorts and a white T-shirt as he held baby Sunny in his arms and soaked up the sun.

After enjoying a stroll along the shore, Elyse and Josh relaxed on the sand with their Weimaraner dog, Harlow.

Elyse and Josh welcomed their first child together on February 25.

The couple announced the birth by posting a photo with their hands on Sunny’s feet to their respective Instagram accounts.

Elyse recently revealed she was crippled by anxiety following the birth of her baby boy.

Speaking to Stellar, she said: ‘I got quite anxious leaving home for the first time. My heart was racing. I didn’t know if I could do it.’

‘Having [Sunny], having our dogs and getting out there… And Sunny was screaming in the car and it made me quite scared.’

She added: ‘I found it hard to breathe and I had to tell myself, “It’s fine, what could go wrong? Everyone has babies… you just have to go for it.”

‘It took a couple of times to feel confident. But I’m not going to lie, it was hard at the start.’
