Vivian, who turned one on 5 December, was unphased by the camera flashes, even turning for one last photo opportunity – and showing off her two front teeth in the process – as her mum put her into a waiting car.
Gisele Bundchen, who also welcomed a son Benjamin in 2009, has said of motherhood: "It takes some adjusting, but it is so, so wonderful."

The supermodel has no worries in that department. She has been happily married to NFL star Tom Brady, and the pair will celebrate their fifth wedding anniversary on 26 February.
