The Kardashian matriarch wrote, "Happy Birthday to my precious Kimberly! @kimkardashian I love and adore you... you have brought so much joy into all of our lives and you are the most wonderful daughter, wife, sister, friend and mom."
She continued, "I thank God every day he blessed me with you and I cherish every single moment and memory. My heart is full of gratitude and I love you more than you will ever imagine or know... Mommy xo."
Kris also shared an adorable home video on Kim's app that features Kim's 2nd birthday party. Her face is priceless when she gets surprised!
Kendall Jenner also took to Instagram Friday morning, posting a throwback of Kim with her and Kylie Jenner as just tiny, little toddlers. She captioned the pic with two, simple heart emojis.
The model also took to her app to share some sweet words for her sister along with a bunch of photos of the two of them together. "Happy birthday, Kim!! I'm lucky to call you my sister," she wrote in the post. "You're such a smart, talented, driven and kind person. You've taught me so much and you'll always be such an inspiration to me. I love you and hope you have the best day!"
Kylie followed in her mom and Kendall's footsteps, sharing another throwback of Kim driving in a car decorated with streamers.
"Happy Birthday Kimberly," she wrote. "I love you sister."
Khloe Kardashian took to her app to shout out to her "amazing, smart, beautiful sister" Kimmy, writing a sweet note alongside the link on Twitter. "Happy birthday @KimKardashian!!! I hope this video puts a smile on your face," she wrote. The video included in the post features Khloe's face photoshopped onto Kim's body while wearing some of her "sexiest looks."
Caitlyn Jenner shared a selfie with Kim, writing simply, "Happy birthday Kim! Love you."
The thoughtful messages are especially important right now as Kim continues to recover following her terrifying robbery earlier this month during which five men gained entry into her Paris apartment and bound, gagged and held her at gunpoint before stealing $11 million worth of her jewelry.
E! News caught up with Kris earlier this week who told us it's been "a process." She said, "One day at a time." She also noted that she has been "doing what a mother does" by having loved ones gather around Kim and making sure she feels safe.
A second insider recently told us, "Kim is doing better but she still has a long way to recover from the robbery. She has been receiving some professional counseling. Her friends and family have been really supportive. Her sisters and mom have been checking on her every day."
Still, Kim decided she wouldn't be making any big plans for her birthday Friday.
Another source told E! News, "Kim's birthday is going to be a very quiet celebration this year. She has no plans on making a big bash. She will have an intimate birthday with her immediate family."
The insider added, "She is not in any celebrating mood yet. Kanye is trying to do whatever he can to make her feel better, but it's just the constant memories of the robbery that keep on messing with her."
