From what I've read recently, the general consensus seems to be that people can usually not recall memories before around 3 years old. With the earliest memories generally between the ages of 3 to 6 years.
Obviously there would be a lot of factors that could influence whether memories are formed retained & recalled.eg trauma etc.
My earliest memory is not super clear, but I recall being prevented from entering the loungeroom & being really frustrated that I couldn't get past the barriers in the doorways. I believe it relates to when the lounge room carpet was being laid.
I would have been around 2 years 7 months old. ( confirmed by mum when she was alive)
What is your earliest memory?
