She's getting so big!
To kick off her special day, the proud mom shared a darling photo of her mini-me that shows the little one with her hair styled in two braids as he hugs and kisses a stuffed dog toy. "Today is her day! Happy birthday my little angel! Hoje é o dia dela! Feliz aniversário minha anjinha!" Bündchen captioned the touching 'gram in both English and her native language of Portuguese.
The football star also shared his own birthday wishes for their only daughter, and posted an adorable photo of Vivian and his wife on his Facebook page that he captioned: "My baby girl isn't a baby anymore... Happy birthday Vivi -- we love you so much!!"
