Indi

Indiana Holden Seinfield or Indi for short, is the one-year-old daughter of Aunt Claire and Uncle Grady. She was mentioned first in the 2015 series when Claire said she was "expecting", and she made her first actual appearance in the 2016 film Blazing Away.

Personality
Indi is innocent, playful, and fun-loving and has a liking for animals, particularly Lightning Blaze. She likes throwing around balls for him to chase and treats him like a best friend. Indi is rarely seen crying, the only time being when Lightning Blaze ran away.

Physical appearance
Indi is chubby with short yellow hair and deep green eyes. She wears her hair in bangs, and is usually dressed in T shirts or overalls.

Appearances
Indi has so far only appeared in Blazing Away, though she was lightly mentioned in 2015 when Aunt Claire said she was expecting.

Trivia

 * I think Indi is literally the first baby to be featured in Doraemon.
