A Special-Needs Child on 'United States of Tara' (VIDEO)

A dinner out is not a simple everyday event on 'United States of Tara' (Mon., 10:30PM ET on SHO). At a restaurant, Tara has turned into her 5-year-old alter personality, happily coloring and wearing the kids-menu paper crown.

Her sister Charmaine is not amused. "What do I do if Tara doesn't come back before the wedding? I'm going to have a giant 4-year-old swimming in my chocolate fountain."

But the waitress thinks she's adorable, paying particular attention to Tara when she brings their orders. "My aunt has a special-needs child," she explains. She thinks Tara is "precious."
