Kim Kardashian lost her cool on on Saturday (30Nov13) after a follower criticised her parenting skills.

The reality Tv star took to the social networking site to tell fans she had taken her daughter, North, swimming for the first time.

She wrote, "We took our baby girl swimming today for the 1st time, she loved it so much! #BestDayEver"

One critic quickly replied, "probably cos she actually got to see her parents for a change!"

The tweet angered Kardashian, who defended her skills as a mother and a devoted partner to her fiance Kanye West.

She wrote, "u sound so ignorant. Bc (because) I don't tweet or instagram my every move w (with) my daughter means I am not with her 247 (all the time)? We share what we want. Or is it bc (because) I go support my fiance at every show & I post pix? When the baby goes down 4 bed or a nap, parents are allowed 2 work & support each other, maybe even have fun too."
