A Toddler With A Mortgage is a character in a work aimed at children who has no explicit age, but can be portrayed as a child or an adult as the situation requires. Often portrayed as an anthropomorphic animal or other non human, the Toddler With A Mortgage may live alone, drive a car, and shop for groceries. At the same time, they may also play with toys, attend kindergarten or elementary school, have playdates with their friends and still be subject to childhood fears. This kind of character is usually found in works aimed at very young children, and intended to be relatable and understandable to them. A character who is explicitly given an age (even if they don't act their age) doesn't count. Compare:
- Vague Age: a supertrope about any character of unclear age
- Wise Beyond Their Years, Child Prodigy, and Adorably Precocious Child: a child who acts older than they are
- Man Child, One of the Kids, or Kiddie Kid: An adult character (or older kid) who acts younger than they are
- Various characters on Sesame Street
- Pee-Wee's Playhouse
- Steve's younger brother Joe from Blue's Clues has both traits of a child and an adult. He lives alone and is played by an adult, but is childish enough to make it unclear what age he is.
