COLORADO SPRINGS, April 7 (UPI) -- A Colorado Springs 4-year-old broke three international records this week in a cup-stacking competition at the Denver Coliseum, a newspaper said.

Miles Seminario has been perfecting his cup-stacking skills for up to three hours a day for the past six months in preparation for the Sunday event, the Denver Post reported. Seminario went up against other cup-stackers aged 4 or less.

"It's kind of silly. He saw a kid stack cups on 'Yo Gabba Gabba!' in November. Now, he's obsessed," the boy's mother said. "Yo Gabba Gabba!" is a television show for children shown aired on the Nick Jr. channel.

Seminario's parents reportedly were hesitant to let him participate in the contest because of the pressures of competition.

Nearly 1,100 people from eight countries and 34 states were involved in the World Championship contest said Matt Reed, executive director for the World Sport Stacking Association.
