Childhood amnesia / 6 or 7 years old

Explanation:

Childhood amnesia refers to the inability of adults to remember memories that have to do with situations or events before the age of two to four years.

It's been noticed by researchers, that in adults the recall of memories before the age of three or four years of age is virtually impossible regardless of the method used to retrieve those memories. Children by the age of 5 have difficulties recalling these memories but sometimes they can recall them. However, as grown adults they will have lose this ability.

Thus, adults generally are unable to remember the personal events that occurred during the first three years after their birth. This specific type of forgetting is called Childhood amnesia and research suggests that the age of people's "first memories" starts at around 6 or 7 years old.
