Kylie Jenner splashes $70k on baby gear

Kylie Jenner splashed $70,000 on her baby and is on a mission to outfit her daughter in the swaggiest baby gear money can buy.

Sources close to Jenner tell TMZ the mom-to-be has made online baby shopping a habit ... surfing the web for high-end designer clothing and baby accessories. She's already got one huge closet filled and plenty more is on the way.

TMZ learned Kylie's dropped about $70k. One Kylie source familiar with the purchases tells TMZ, "This is gonna be the best dressed kid you've ever seen."

As for a baby shower -- our sources tell us nothing's set in stone -- but you gotta imagine Kris and Kylie's sisters will plan a hell of an event.
