Gwen Stefani shares a smile as she totes her 4-month-old son Zuma Nesta Rock on their way to her parents’ home in Los Angeles on Christmas Day.

Accompanying the singer, 39, was husband Gavin Rossdale and son Kingston James McGregor, 2 ½. Gavin recently explained to Babble Baby that he hopes for his boys to question things — in a good way.

Gwen carries Zuma in a Brio car seat.
