Kylie Jenner threw back-to-back themed bashes for Stormi and Aire, who were born only a day apart, and she documented the festivities on her Instagram.

For Aire’s gathering, Jenner threw a Minion-themed soirée, which she documented on Instagram, capturing pics of themed balloons and blue-and-yellow wrapping paper and tableware. She even recruited people to dress up in Minion costumes, and she got a video of Aire’s cousin, Tatum, dancing along with the giant mascots.
