Kourtney Kardashian shared a rare glimpse of her life with her four-month old son, Rocky Thirteen, in a sweet Instagram slideshow on Wednesday.

In addition to sharing snaps on a walk with her husband Travis Barker and their baby boy, the 44-year-old reality star uploaded a picture of her pumping breastmilk while rocking a sexy black lace bodysuit and kitten heels.

‘That’s life,’ she captioned the post, which featured her soaking in quality time with her family, rocking a pair of black Christian Louboutin heels and posing for a glamorous selfie.

The mother-of-four also included a precious image of Rocky’s hand holding the chain necklace around his dad’s neck.

Kardashian’s pictures appeared to be taken throughout the past month as she included a view of her staircase full of red roses on each step seemingly from Valentine’s Day.

A number of the Keeping Up With the Kardashians alum’s followers flocked to the comment section to praise her for a sharing a snap of her ‘real mum body.’

One fan gushed: ‘Love your pump shot! ‘

A third asked: ‘Who says pumping can’t be sexy?’

‘That’s my sister!!!’ her younger sibling, Khloé Kardashian gushed underneath the slideshow.

Others, however, ‘why’ she was sharing a photo of herself ‘pumping breast milk.’

‘It’s such a personal private intimate thing,’ one commentor inquired. ‘But I guess everyone sees it differently. God bless you and your family. Very happy for you all.’

Another critic wrote: ‘the pumping photo really??? smh [shaking my head].’

Her followers fiercely defended her against the small handful of trolling comments, with one stating ‘it’s a normal mom thing’ and that breastfeeding needs to be ‘normalized.’

Last month, Kardashian shared her postpartum tips on clothing, hair, make-up and breastfeeding.

‘Getting dressed postpartum while breastfeeding [equals] throwing on an oversized coat, flat shoes pretty much always,’ Kourtney wrote on her Instastory.

‘[I love] leggings, sweats – anything baggy and comfortable aka husband’s vintage T-shirts and Dickies. Anything super fast to throw on. [The] less time away from my baby the better.’

Kardashian then described her two-minute hair and make-up routine which included her half-sister Kylie Jenner’s $18 ‘High Gloss’ lip gloss, a dab of $30 Kosas ‘Revealer’ concealer, a lash curler, one coat of mascara, and an eyebrow brush.

The Kardashians producer-star lets her hair air dry ‘however it wants’ with no product: ‘[It] used to be super straight but after I [dyed] her blonde she’s got some texture.’

As for postpartum hair loss, Kourtney recommended fans use $40 Lemme ‘Mama’ from her vitamin and botanical supplement company.

‘So I took @lemme mama during my pregnancy and still take it daily postpartum and I haven’t noticed hair loss this time so far,’ Kardashian wrote.

‘I do take other supplements too (vitamin D/K, calcium/magnesium, omega 3, probiotics, iron, B complex).’

The Poosh founder also gave a long list of foods that might boost a nursing mother’s breast milk supply recommended by her nutritionist Leona West Fox.
