Santa hosted his young guests at the mall's Microsoft Ice Palace which features a 30-foot ice dome with falling snow, light shows and interactive displays.
Susie Brown of Springfield brought her deaf 9-month-old daughter and her hearing older child to visit with Santa and his signing elf.
It's important to support any event for the deaf and hard-of-hearing, Brown said. Her 6-year-old son has apraxia, a muscle coordination disorder that makes it difficult to speak, but he already knows some sign language, she said.
He unfortunately couldn't meet the signing Santa on Wednesday because he was in school, she added.
Nicole Warman said she drove all the way from Frederick, MD to bring her children, 3-year-old Tyler and 4-month-old Parker to see Santa.
Warman said she is deaf, but both of her children are hearing.
Ed Cassidy, marketing and sponsorship director at Fair Oaks Mall said he'd seen many deaf parents and grandparents on Wednesday bringing their hearing children to see Santa.
Ashburn-based HIS Sign, provided sign language interpreting services during the event. "It gives every child the opportunity to enjoy Santa," said Ron Burke, COO of HIS Sign.
A non-signing Santa Claus will be taking Christmas wishes until Dec. 24 at Fair Oaks.
