It looks like Kylie Jenner was feeling nostalgic yesterday. It may not have been Thursday, but that didn't stop the star from taking to Instagram to share an adorable throwback snap of herself and sister Kendall Jenner last night.

In the 'gram, a very young Kendall and Kylie are pictured sleeping in white hampers placed side by side—although it's hard to tell if they're actually asleep or simply posing for the camera as the photo was posted without a caption. The siblings have ribbons braided into their hair and seem to be tuckered out from a day of fun. Oh, to be young again.

But this isn't the first time Kylie has 'grammed their childhood pictures. A few weeks ago, the younger Jenner sister shared several stylish shots of them as little girls.
