Who wouldn't want to go on a 24-hour girls' ski trip to celebrate a friend's birthday?! Not Kylie Jenner, apparently!

This mommy's putting her almost year-old daughter Stormi at the top of her list of priorities and partying with her pals has slid waaaay down on the list.

The makeup mogul posted to her Instagram story that after 24 hours with BFF Jordyn Woods, celebrating her friend's little sister Jodie's birthday with a ski trip to Mammoth Mountain, she was really missing her little girl.

In fact, baby Stormi is so much Kylie's focus that mama is already preparing for her little one's first birthday on February 1st. Jenner posted, "already wrapping Stormi's bday gifts," Kylie told her followers on Instagram Story. "I'm too excited." She also revealed that little Stormi is still opening up some of her Christmas gifts! Excess, anyone?
