Kim Kardashian is a ''strict mother''.

The 33-year-old reality TV star has certain routines she likes her 12-month-old daughter North, with whom she has with her husband Kanye West, to follow every day and she doesn't allow her to sleep in their bed, unlike her sister Kourtney and partner Scott Disick do with their kids Mason, four, and Penelope, 23 months.

She explained: ''I am a strict mother. I'm really fun and playful, but I'm really strict on nap time, and sleeping in her own crib.

''Like Kourtney's style is where her kids sleep in bed with her, so especially with the third baby coming - they're going to need a bigger bed or they're going to need some other rules.

''And maybe on weekends, [North will] come and sleep in the bed with us. But ... I'm not crazy strict.''

Meanwhile, the brunette beauty admits she and Kanye, 37, who married in Italy last month, are planning to have at least one more child as they'd like to have a little sibling for North.

Asked whether she would like a brother or sister for North, Kim told the MailOnline: ''I hope so. I grew up with a lot of siblings so I know what that's like. I don't know if I would really follow in my mum's footsteps and have six; that's a little crazy. I don't know how they did it - they were in their 20s and they weren't really thinking right! I like a big family and I would definitely like one more and see how that goes.''
