Megan Gale can't stop sharing her joy at being a first-time mum.

The 38-year-old Perth model has shown off the first photos of herself with her newborn son River.

Gale and her partner Shaun Hampson, 25, welcomed River into the world on May 13.

Yesterday the David Jones ambassador shared an intimate photo of herself and her bub in a baby-wrap carrier to her 160,000 Instagram followers.

She said trying out the baby carrier was "like learning how to do origami".

"But once you have it on and bub inside OH MY GOD," Gale wrote on Instagram alongside the photo.

"Such a relief and a load off my shoulders, arms and back plus it's almost like having him in my tummy again!! Also I have my hands freed up to get more stuff done #wishidtrieditearlier."

Since his arrival, Gale has posted a number of snaps of River on Instagram including one where he is seen sporting a Richmond scarf, his proud dad's AFL team.
