Although the reality TV star and her rapper boyfriend Travis Scott, 25, have previously given glimpses of their baby, sharing pics of her hands and feet, the new mum has also posted a full-length photo of her daughter to social media for the first time.
Jenner captioned her photo of Stormi: "My angel baby is 1 month old today."
The adorable photo came just hours after Scott took to Snapchat to celebrate his daughter turning one month old, writing "my lil mama 1 month today," along with a close up of Stormi's sweater that reads 'DADDY'.
"Her favourite unit of course," Scott added, likely referring to the term "parental unit."
The happy couple, who have been dating for nearly a year, welcomed their first child on February 1.
Three days after her birth, Jenner announced the baby's arrival after many months of speculation she was expecting.
She went to great lengths to hide the news from the world's media so she could 'enjoy the experience' of pregnancy in private.
