In a video posted by Vanessa on Instagram, 11-month-old Capri is seen standing in front of her aunt Sophie before walking to her mom.
The women are then heard cheering the milestone as Vanessa embraces a smiling Capri.
The 37-year-old mother wrote, "My baby!!!! So proud of my Koko Bean ... Capri took her first steps from her auntie Sophie to mama today."
Kobe and Vanessa would have celebrated their 19th wedding anniversary on April 18. Vanessa shared a photo of Kobe with her 14 million Instagram followers on the couple's wedding anniversary.
