Gwen Stefani celebrated Zuma's first Thanksgiving with a low-key day out at the park. 

And the new mum was well equipped with nappies as she carried Zuma in his car seat to a bench at Coldwater Canyon park in Beverly Hills.

Husband Gavin Rossdale kept eldest son Kingston occupied with a playdate by the swings, whilst mommy looked on with the new baby.

Gwen - who gave birth in August - dressed down in Adidas sports pants, but still wore her trademark red lippy.
