Gwen Stefani took her new son Zuma Nesta Rock Rossdale for a play in the park in LA yesterday.

Dressed in an adorable all-in-one suit, the newborn enjoyed a day at the park with mum, older brother Kingston and some friends.

But the two-month-old tiny tot couldn't take all the excitement and slept most of the day.

As Zuma slept soundly, Gwen had bags of energy to play with Kingston and his friends.

Last week the newborn made his A-list debut, meeting Courtney Cox and Cindy Crawford at Kate Hudson's Halloween party.
