Do child actors (eg Sunny from A Series Of Unfortunate Events) remember acting after they’ve grown up?

Alan Chenkin, Learned about celebrities by reading the tabloids in the checkout aisle.

Most child actors under the age of six or seven have a limited memory of events, (It varies with the child),  – and most child actors have visual records (Movies or film images) that refresh and renew their memories of acting events.[1][2]
Here are some reminisces:
You may remember this child star from the Harry Potter films:
Daniel Radcliffe is enjoying a strong career in acting as an adult, where he has been in many films and even on Broadway.  Emma Watson, also of Harry Potter fame, enjoys a strong career and is a strong voice for feminism.
Neil Patrick Harris, Child star and successful performer today!
Neil Patrick Harris movies and more are available on Amazon, and eBay.
Here is some more information on Presley Smith, who played Sunny Baudelaire, in the NetFlix TV adaptation of “a series of unfortunate events
Presley Smith, born June 28, 2015, is a Canadian child actor and obviously too young to be asked to reminisce about her role.  Her family is keeping her private life  out of the spotlight, hoping to avoid any spectacle resulting from her acting work.  You can find the series on Netflix, and tie-in DVD’s on Amazon.
Here’s hoping that all the child stars have bright careers and futures, without the glare of spotlights and armies of paparazzi following them!  Having a good upbringing is the best defense against the tragedies of many child stars, who may not be in the limelight – but try to live a normal and productive life.
