Little Suri Cruise may not realize the effort involved, but her family made sure she celebrated her first birthday in style.

Tom Cruise and Katie Holmes organized a birthday lunch on April 18 at the Cruise compound in Los Angeles, where the entire clan dined on pizza and cupcakes from Sprinkles bakery in Beverly Hills.

"Suri is walking and talking," says a source close to the family, who adds that dragonfly and butterfly piñatas were part of the entertainment.

The guest of honor – who, Holmes told PEOPLE recently, "loves just being outside right now," received a gym set for the backyard, according to the source, along with a stack of books, balls and dolls.

"Tom and Suri kicked the ball around the lawn during the party," adds the source.

Holmes's mom Kathy, 60, flew to California for the occasion, as did a sister and nephew of Cruise, according to the source. On April 17, both grandmothers – Kathy Holmes and Mary Lee Mapother South, 70 – were treated to dinner at an Italian restaurant.

Just days earlier Holmes, 28, was in Shreveport, La., where she is filming Mad Money with Queen Latifah and Diane Keaton – and the day after the birthday bash, she and Cruise, 44, jetted to New York City for Cruise's 9/11 Detox Fund-Raiser.

But Wednesday's luncheon was a fun break from all the jet-setting – albeit a messy one. By the end of the party, says the source, "Tom, Katie and Suri were wearing chocolate."
