Los Angeles, June 12 (IANS): Reality TV star Kim Kardashian West and husband Kanye West are planning to enrol daughter North into "big sister classes" to ease the adjustment when their second child arrives.

"Kim has signed Nori (North) up to big sister classes. She will have one-on-one sessions, as well as group classes. Part of the sessions will involve playing with dolls," a source told Heat magazine, reports femalefirst.co.uk.

While many new parents save cash by using their first child's clothes again, the "All day" rapper is insisting on a brand new designer wardrobe for their second baby because he doesn't want the tot to develop an "inferiority complex".

The source added: "Kanye is refusing to let the baby wear North's clothes in case it gets an inferiority complex. He's planning to drop about $1.5 million on designer threads."

Apart from splashing out on a new wardrobe, the 37-year-old rapper is said to be "scouring the world" for the perfect nursery furniture.

"He's completely overhauling a guest room and turning it into a nursery. He's set a budget of $1 million for the room and furnishings," said the source.
