North West is growing up fast.

And her mom, Kim Kardashian, is keen on sharing her progress, posting a new photo of her daughter, seated on a green sofa, on Instagram Tuesday with a very simple caption: 'LOL.'

Since North's birth in June, Kardashian, 33, has offered up only a few glimpses of her sweet daughter, who turns 5-months old on Friday - far fewer than the sexy selfies the reality and fashion star has been fond of posting to social media to show off her successful post-baby weight loss.

In Kardashian's latest snapshot, baby North is all smiles, showing off big brown eyes that have prompted mom's followers gush that she's 'precious' and 'gorgeous.'

Earlier, the happy mom also posted another photo of her baby girl, this time comfortably lounging in the arms of pal Riccardo Tisci, the creative director of Givenchy.

'#NewStylist,' she playfully captioned the pic. (And what a stylist, to boot!)

No word yet on whether the growing infant will be tapped as a tiny flower girl for the nuptials of her newly engaged mom and dad, Kanye West. The rapper offered the first glimpse of his baby girl, then 10 weeks old, to the world when he showed off a proud snap on grandmother Kris Jenner's talk show in August.

Grandpa Bruce Jenner offered up nothing but praise for Kardashian's maternal skills on Monday at the All Sports Film Festival in Los Angeles, saying she's 'doing a great job' as a mother.
