But still, her decision was long term.
"I lasered my baby hairs off years ago, because my forehead had all these little baby hairs, and I would always break out because of them," she said on her subscribers-only app and website, adding that she also lasered her neck.
"I had such a hairy neck," she wrote.
Most people wouldn't know that she had the vanity issues though, thanks to photo editors.
"Every photographer would photoshop them out anyway," she wrote, "and I thought I looked better without the baby hairs, but now I miss them."
Why does she miss that peach fuzz?
"I think they look youthful!," she wrote, before adding a bit of a disclaimer. "So ladies, you can always laser your hairline, but I miss mine."
One thing she's not missing is her baby weight. Kim has been feverishly getting her body back after giving birth to son Saint.
The reality star showed off her post-baby weight after Justin Bieber's concert in Los Angles in Los Angeles, stepping out in a body-hugging black skirt, matching sheer top and black bra in late March. That same week Kim revealed that she's getting closer to her target weight following the December birth of son, Saint West.
"Getting back in shape after I had North was SO tough," she said on her blog. "I'm in the middle of doing the same thing right now after having Saint, and I'm so excited that I'm 42 lbs. down!"
Kim has said that her ultimate goal is to drop 70 pounds.
"Wearing my old workout clothes! They fit again," Kim proudly shared, adding that she wanted "more things to start fitting."
She's reportedly losing her weight by adhering to the Atkins 40 diet, which is high in protein but also allows more carbs than normal since she was still breastfeeding. She used Atkins following North's birth, too.
