Last Friday, Kourtney Kardashian Barker received substantial backlash over neglecting to put her 21-month-old son Rocky Thirteen Barker in a life vest while aboard a small boat during their family vacation in Coeur d’Alene, ID.

Idaho state law mandates that ‘all children under the age of 14 must wear an approved life jacket when they are aboard a boat 19 feet in length or less whenever the boat is underway or under power.’

The 46-year-old reality star boasts 283.4M social media followers – many of whom were concerned and outraged – like user @janettparks, who commented: ‘Child endangerment per Idaho law.’

‘Please, please put a life jacket on that sweet babe!’ Instagram user @bcudini agreed.

‘What no life vests?’ Instagram user @calkins5039 blasted. ‘Isn’t that against the law?’

Instagram user @sue_branagan commented: ‘POV Please use a life vest on your child. In that huge boat accident in Tahoe, the only two people that survived were wearing life vests. All the rest died when the boat capsized.’

‘Protects her son’s face from the internet but doesn’t protect him from possibly drowning… priorities,’ Instagram user @lifeofrylee84 scoffed.

Instagram user @danielle_mamma_of_two wrote: ‘No life jacket? And the mother of the year award goes to…’

On Saturday, Kourtney announced that she had officially purchased a $69.99 Stohlquist ‘Infant’ life jacket that ‘fits’ little Rocky.

‘Good looking out. Honestly, didn’t think about some of the dangers,’ Kardashian wrote in response.

‘Thank you for making me aware and hopefully this helps make other mommies aware of the dangers of certain types of boating without a life vest.’

The Calabasas socialite and her son were joined in Idaho by her neighbor-turned-husband Travis Barker, whom she wed three years ago.

Kourtney shared one snap of herself seated next to the 48-year-old Grammy-nominated drummer’s 26-year-old stepdaughter Atiana De La Hoya, who’s biological father is retired boxer Oscar De La Hoya.

Missing from the woodsy family fun were Travis’ two children – son Landon, 21; and daughter Alabama, 18 – from his three-year marriage to Miss USA 1995 Shanna Moakler, which ended in 2008.

Kardashian also welcomed three older children – daughter Penelope, 13; son Mason, 15; and son Reign, 10 – during her on/off nine-year relationship with Talentless CEO Scott Disick, which ended in 2015.

Barker will host four upcoming 5K Run Travis Run races starting with September 20 at Jackson Park in Chicago, and tickets range between $59-$1,680.

The half-Armenian beauty will soon begin production on the seventh season of her family’s Hulu reality show, The Kardashians.

Kourtney was technically the first member of her family to star in a reality show – The Simple Life-inspired eight-episode series Filthy Rich: Cattle Drive, which aired in 2005 on E!

Kardashian happens to be one of the few college graduates in her family as she holds a bachelor’s degree in theatre arts from the University of Arizona.

The 5ft brunette keeps busy running her lifestyle website Poosh and her sugar-filled vitamin and botanical supplement company Lemme.
