He may only be five months old, but Mason Dash Disick already looks pretty dashing in his toddler clothes.

The son of US reality TV star Kourtney Kardashian and boyfriend Scott Disick has been pictured wearing trendy jeans and matching grey polo shirt and flat cap.

Proud mum Kourtney revealed the snaps on her new blog for the People magazine website, where she discussed the trials and tribulations of parenthood.

She said she is not surprised that motherhood has changed her life, adding that she did not expect even the small details to be altered so drastically.

Her famous sisters Kourtney and Khloe are just as besotted with the tot, regularly showering him with kisses.

"My son changes so much every day. I could stare at him for hours! He has brought more love and joy into my life than I ever imagined," Kourtney wrote.

Earlier this year, the model and socialite was snapped taking Mason for a walk through Beverly Hills, where he wore snuggly toddler clothing.
