"Every single day I hope you realize how much you matter to us all. How much we cherish and respect you! How lost we would be without you in our lives. You are the belle of the ball! The queen of hearts! The life of every party! My heartbeat! My teacher! You are all that matters to us! Without you, our lives would feel aimlessly lonely," Khloé continued.

"You have so many gifts and one of them is making us all feel loved, seen, validated and heard. I don't know how you do it but you do every single day! you inspire and motivate me daily. You've taught us so many things. I don't think we have space for me to write them all down But one of the most precious things you taught me is how to love," the mom of one said.
