Halle Berry is ''healthy and happy'' following the birth of her son.

The 47-year-old actress insists she's not stressing over her postpartum pounds after welcoming her second child Maceo-Robert, whom she has with her husband Olivier Martinez, into the world last October.

Speaking to PEOPLE.com, she said: ''I'm healthy and that's really good. When you're nursing you can't really diet because you have to keep producing milk ... I'm healthy and I'm happy and that's all that matters.''

The brunette beauty - who also has six-year-old daughter Nahla from her previous relationship with Gabriel Aubry - believes Maceo has brought ''joy'' to her family and she is overwhelmed by the love she feels for him.

She explained: ''[Maceo's] perfect, just perfect. More love, more joy -- having a new baby in your family brings that.''

However, Halle admits she and Olivier, 48, whom she married last July, are still trying to find the balance between parenthood and their demanding careers.

She added: ''[A new baby means] less sleep. And I'm working on the TV show ['Extant']. It's a new grind, it's a new rhythm.

''We're trying to get used to that. [But] we're managing.''
