Jennifer Garner has showed off her post-baby body just two weeks after giving birth.

The actress welcomed son Samuel on February 27 who joins her two other children with actor Ben Affleck; Violet, six, and Seraphina, three.

The busy mother-of-three carried out chores with her eldest child in Pacific Palisades yesterday.

With a newborn it is unlikely she is getting much sleep so the 39-year-old covered up her eyes with dark glasses.

She wore loose jeans, a blue and grey sweater and a baggy jacket.

Violet proudly carried a baby doll in a toy car seat and looked like she had gotten into the spirit of being a big sister to her new brother.

The mother-daughter duo later went to meet up with proud father Ben who is said to be thrilled to finally have a son.

"He couldn't be happier. He loves his wife. He loves his family and he's proud he's legitimately proud you can just see it," a source close to Ben told People.

"He gets to spend a lot of time with his family and the idea that they have three kids right now is something that makes them both feel really good."

Jennifer was first seen post-baby last Wednesday driving around in her Land Rover while Ben was also seen that day looking sleep deprived and smoking a cigarette.
