The term child actor or child actress is generally applied to a child acting on stage or in motion pictures or television, but also to an adult who began his or her acting career as a child; to avoid confusion, the latter is also called a former child actor. Closely associated is teenage actor or teen actor, an actor who reached popularity as a teenager.
Many child actors find themselves struggling to adapt as they become adults. Lindsay Lohan and Macaulay Culkin are two particular famous child actors who eventually experienced much difficulty with the fame they acquired at a young age; Lohan's career resumed after an interruption of several years. Many child actors also become successful adult actors as well, an example being Mickey Rooney's career that included both the popular 1935 film A Midsummer Night's Dream and the popular 2011 film The Muppets.
Regulation of child actors
In the United States, the activities of child actors are regulated by the governing labor union, if any, and state and federal laws. Some projects film in remote locations specifically to evade regulations intended to protect the child. Longer work hours or risky stunts prohibited in California, for example, might be permitted to a project filming in British Columbia. US federal law "specifically exempted minors working the Entertainment Business from all provisions of the Child Labor Laws." Any regulation of child actors is governed by disparate state law.
Due to the large presence of the entertainment industry in California, it has some of the most explicit laws protecting child actors. Being a minor, a child actor must secure an entertainment work permit before accepting any paid performing work. Compulsory education laws mandate that the education of the child actor not be disrupted while the child is working, whether the child actor is enrolled in public school, private school or even home school. The child does his/her schoolwork under the supervision of a studio teacher while on the set.
Issues involving child actors
Ownership of earnings
Many child actors never got to see the money they earned because they were not in charge of this money. Jackie Coogan earned millions of dollars from working as a child actor only to see most of it squandered by his parents. In 1939, California weighed in on this controversy and enacted the Coogan Law which requires a portion of the earnings of a child to be preserved in a special savings account called a blocked trust.  A trust that is not actively monitored can also be problematic however as in the case of Gary Coleman who after working from 1974, later sued his adoptive parents and former business advisor for $3.8 million over misappropriation of his trust fund.
Some people also criticize the parents of child actors for allowing their children to work, believing that more “normal” activities should be the staple during the childhood years. Others observe that competition is present in all areas of a child’s life—from sports to student newspaper to orchestra and band—and believe that the work ethic instilled or the talent developed accrues to the child’s benefit.
The child actor may experience unique and negative pressures when working under tight production schedules. Large projects which depend for their success on the ability of the child to deliver an effective performance add to the pressure.
Examples include the cast members of the American sitcom Diff'rent Strokes, which starred child actors Todd Bridges, Gary Coleman, and Dana Plato. Plato went on to pose for Playboy magazine and was featured in several softcore pornography films. She was arrested twice for armed robbery and forging prescriptions, and died in May 1999 from an overdose of prescription medication, deemed suicide. Coleman famously sued his parents for misuse of his trust fund and, although awarded over $1,000,000, filed for bankruptcy in 1999. After many charges of assault throughout the next years, Coleman died in May 2010. Bridges was plagued with many legal troubles as well as an addiction to cocaine. After breaking this habit, he traveled across the U.S., touring schools and warning about the dangers of drug abuse. He has since made several cameo appearances on multiple television programs.
The popular television sitcom Full House made child stars out of Jodie Sweetin and the Olsen twins. After the show, Sweetin went on to develop an addiction to methamphetamine, as well as alcoholism. She later overcame this and wrote a memoir describing her experiences. Mary-Kate Olsen and Tracey Gold (Growing Pains) developed eating disorders, for which they were treated with intensive rehab. Anissa Jones, of Family Affair fame, overdosed on August 28, 1976 at age 18.
Jonathan Brandis, who appeared in a number of films as a child and teenager, committed suicide in 2003 at the age of 27 due to reasons possibly related to his lack of continued success into adulthood. Likewise, Sawyer Sweeten, a child actor who portrayed Geoffrey Barone on the American sitcom Everybody Loves Raymond, took his life in 2015 at the age of 19 after a period of depression.
Drew Barrymore was notorious for her illegal and public antics beginning shortly after her first role in E.T. the Extra-Terrestrial. Barrymore admits to smoking cigarettes at age nine, drinking alcohol by the time she was eleven, smoking marijuana at the age of twelve, and snorting cocaine at the age of thirteen. At the age of fourteen, she attempted suicide.
Another popular example today of child actors with post-success troubles would be Lindsay Lohan. Famous for her starring roles in The Parent Trap (1998), Freaky Friday (2003), Confessions of a Teenage Drama Queen (2004), Mean Girls (2004), Herbie: Fully Loaded (2005), Just My Luck (2006) and Georgia Rule (2007), Lohan has since run into much trouble with the law. In May 2007, Lohan was arrested on a charge of driving under the influence of alcohol (DUI.) Lohan entered the Promises Treatment Center rehabilitation facility where she stayed for 45 days. In July of that year, less than two weeks out of rehab, Lohan was arrested a second time on charges of possession of cocaine, driving under the influence and driving with a suspended license. In August, Lohan pleaded guilty to misdemeanor cocaine use and driving under the influence and was sentenced to an alcohol education program, community service, one day in jail, and was given three years probation. The same month Lohan entered the Cirque Lodge Treatment Center in Sundance, Utah for a third stint at rehabilitation, staying for three months until her discharge in October. In November Lohan served 84 minutes in jail. A sheriff spokesman cited overcrowding and the nonviolent nature of the crime as reasons for the reduced sentence.
There are many instances of troubled adult lives due to the stressful environment to which child actors are subjected. It is common to see a child actor grow up in front of the camera, whether in films, television shows or both. However, it is not uncommon to see child actors continue their careers throughout as actors or in a different professional field.

Mary-Kate Olsen was treated for an eating disorder, deemed anorexia, but her twin sister remained less troubled. In an article with the magazine Marie Claire, Mary-Kate expressed the bittersweet nature of the twins' childhood. "I look at old photos of me, and I don't feel connected to them at all," she said. "I would never wish my upbringing on anyone... but I wouldn't take it back for the world." The twins now have continued success in the fashion industry with an estimated net worth of approximately $100 million.
