North West is too small for her designer clothes.

The daughter of Kim Kardashian and Kanye West was born five weeks premature on June 15 and although her parents had splashed out on a number of designer outfits for the tot, she is too small to wear any of them yet.

A source told US Weekly magazine: ''She's so tiny she can't wear any of the outfits yet. She literally is in plain onesies and is spitting up on everything.

''They'd already purchased about $25,000 in clothes for North. Kanye spent at least a couple of grand at Lanvin and Kim spent about twice that on Hermes goodies. Basically anything that Hermes has for babies, she bought it.''

Meanwhile, Kim and Kanye are embracing parenthood and love taking naps with the tot.

The insider added: ''Kim, Kanye and North always take naps together. The three of them just cuddle up and hang out. Kim enjoys all the different parts of being a mom and the way Kanye is around the baby would just melt your heart. He's always kissing her.''
