Kylie Jenner marks Stormi’s first birthday with adorable never-before-seen photos

"Every day with you is the best day of my life."

Kylie Jenner has marked her daughter Stormi's first birthday with a series of never-before-seen photos. The 21-year-old and her boyfriend, Travis Scott, welcomed their first child together on February 1 last year. To mark her little girl's milestone, Jenner took to Instagram on Friday to share an adorable tribute to Stormi. She wrote:

"How did I get so lucky to have such a sweet, smart, happy baby. "I just couldn’t have dreamt you up, Storm. O wish you could stay this little forever and I could protect that contagious smile and laugh of yours. "I know you won’t remember much about the first year of your life but I pray that you’ll never forget to keep sharing your joy and laughter with the world. "My love grows for you a thousand miles a minute. Every day with you is the best day of my life. Happy birthday to my angel on earth."

It comes as it was reported that Kylie had spent "months" planning her daughter's first birthday party. A source told Entertainment Tonight: 

"Kylie and Travis are planning to throw Stormi a major first birthday. "Kylie has been planning to party for a few months now, and can't wait for the big day. Kylie has always wanted to be a mother but she never knew the satisfaction would be this great. "Kylie will have a themed party with all her family and some of her close friends. It's a very special day for the family.”
