Kim Kardashian West became less ''protective'' of her daughter because it was ruining her social life.

The 'Keeping Up with the Kardashians' star initially wanted to keep 20-month-old North - her child with husband Kanye West - out of the spotlight but had a change of heart when she realised how difficult it was for her and her little girl.

She said ''At first I was like, 'I'm not going to Instagram photos' or I'm going to try to totally change my life but it was really prohibiting me from spending time with my friends and having my daughter grow up with my friends' kids, so I'm a lot less protective than I was.''

The 'Keeping Up with the Kardashians' star says she and Kanye are ''obsessed'' with their little girl and she never expected to be as affected by parenthood until she gave birth.

She told Australia's Daily Telegraph's Sydney Confidential column:

''I am just so obsessed with being a mum, more than I ever thought.

''Everyone has a story that they want to tell you when you're pregnant and, for me, my pregnancy was not the best or the most fun so I didn't want to hear any of it.

''After having her, your whole world changes. I am just so obsessed with her, me and my husband are, we wake up every day and talk about her and how much we love her. It is fun.''
