Earlier this week Jenner celebrated the baby’s milestone with a snap of herself cradling her.
The mother-daughter image was posted after Jenner, 20, showed off her post-baby body on Snapchat.
Jenner returned to the social network after it lost around 1.3 billion US dollars (£930 million) in market value after she tweeted that she was no longer using it.
She had spent months out of the spotlight as speculation grew that she was expecting her first child.
Jenner said she had kept the pregnancy to herself because she wanted to “prepare for this role of a lifetime in the most positive, stress-free and healthy way” that she could.
