Kim Kardashian West says people thought she faked her son Saint.

The 35-year-old reality TV star rarely posts about her seven-month-old son on social media and claims her reluctance to do so made some people think he didn't exist.

Speaking at the BlogHer conference in Los Angeles, Kim said: ''If you don't share something, it's like it doesn't exist.

''I wasn't posting about my son because I want him to go to the park like every normal human being. But some people thought I had a full fake baby because I wasn't posting.''

And Kim also insisted that she and her sister Kourtney Kardashian are adamant that their children are not used in plotlines on their reality TV show.

She said: ''I'm protective of my life with my kids. You might see them on the 'Keeping Up With The Kardashians' a bit, but not real stories.

''Selfishly, I am lucky they can be in the other room while I'm filming. Kourtney and I don't have stories about our children. That is one thing I don't share.''

And Kim wants her children to have ''as normal a life as possible''.

The star - who is married to rapper Kanye West - said: ''I hope they learn to understand they can do anything they want to do and to always be kind. You can't underestimate kindness.

''I hope they are good people and live as normal of a life as possible.

''I hope they are outspoken and follow their truths. I hope they see no one is perfect. Everyone makes mistakes. You can get through anything.

''As long as you surround yourself with family and friends and try not to make the same mistake twice. Learn from your mistakes and grow from that.''
