This seems a little risky, but she looks like she knows what she's doing!

Gisele Bundchen is currently on vacation in Costa Rica, and the supermodel must have a more relaxed attitude towards parenting on her getaway, because she rode around on an ATV with daughter Vivian Lake, who was not wearing a helmet!

Once the Victoria's Secret stunner made it to the beach, she showed off her unbelievable body as she splashed in the surf with her baby girl. Little Viv is walking finally!

During her vacay, the Brazilian bombshell also made time for work by posing for a sexy bikini photoshoot.

What a rough life!
