“ 2/2/22,” Jenner captioned the black-and-white photo of her newborn’s hand.

Jenner, 24, also uploaded Instagram Stories of flower arrangements given to her son's birth, including one from half-sister Kim Kardashian and her four children.

“Congratulations Travis, Kylie and Stormi!” a card sticking out of a bed of purple roses read. “We are so excited and love you so much. Kim, North, Saint, Chicago and Psalm XOXO.”

Her mother, Kris Jenner, also re-shared Kylie’s announcement on Instagram, writing, “My beautiful grandson!! God is so good  #repost @kyliejenner  2/2/22.”

Kylie was pregnant for the second time in August 2021, according to GAG, with a source telling us that the whole family was "thrilled" to have another child on board.

Just weeks later, the former "Keeping Up With the Kardashians" actress verified our news by showing off her baby belly in an Instagram video uploaded in early September. Kylie exposed fans to a very public pregnancy after announcing the news herself, unlike her first, which was kept completely hidden until she revealed Stormi's birth.

Kylie used stunning ensembles to show off her baby belly, most notably a transparent lace bodysuit at New York Fashion Week in September.

However, Kylie eventually concluded her pregnancy in hiding when Scott's Astroworld concert ended in tragedy with the deaths of ten fans. The 30-year-old "Sicko Mode" rapper stated that he "wasn't aware" of the crowd crush while on stage.
