Dr. Dorfman says that “Memory researchers report that small children can retain memories from around 20 months, though they typically fade between the ages of 4 and 7 years old.” That tracks with my son, who really started losing those early memories in the past few years; now, they’re all but gone. She continues, saying, “Infants and toddlers do have memory systems, but many factors influence whether they are stored in long term memory.” Dorfman notes that one of these factors is “the emotional significance of the event,” such as the birth of a sibling. Also, as memory is developing, so is their grasp of language, and their ability to manipulate that language into coherent conversations surrounding an event.
