"Thank you auntie Fafi for capturing this special moment," Bundchen captioned the photo, which she posted Saturday.
In the photo, she can be seen in a crouched position with one leg curled underneath her, one leg stretched behind and arms raised to the sky. Baby Vivian almost has the move perfected, kneeling on her knees with her arms in the air, E! Online reported.
It's not the first time the supermodel has taken to Instagram to show off her mommy-daughter yoga sessions.
On Oct. 1 she posted a photo of the two in matching meditating poses, backs to the camera, looking out a window.
"Good morning! Getting ready for work. #quickmeditation#grateful," she captioned the photograph.
In June, Bundchen posted another photo of herself at a swanky yoga studio, striking a pose, while Vivian sits next to her surrounded by some pillows.
Vivian is Bundchen's youngest child with New England Patriots quarterback Tom Brady. The couple also have a 3-year-old son, Benjamin.
