Refreshing!

Zuma Nesta Rock Rossdale lifts his foot for a sand bath from mom Gwen Stefani while playing at Coldwater Canyon Park in Beverly Hills, Calif. on Sunday.

The 14-month-old then made his way over to an animal statue, which he climbed all over — see the extended post!

On Tuesday, she Tweeted, “songwriting can be fun!! what a great day with tony and tom – writing new no doubt! one day down – back at it tomorrow gwenx”
