Says the researcher: "My own son’s first memory was from the age of 22 months. Children who are 2 often remember pieces, three-year-olds have a lot of memory ..."

I'd be interested in seeing the research on that--not the numbers of people who say "I remember", but how researchers know for sure.  Many people claim to "remember" things in early life, but what I think they REALLY remember is what they were told about their pre-5 year old self by others--parents, in particular. Call them "second-hand memories."

If I can't remember anything younger than, say 3.5 years--safe age, in my instance--what's wrong with me, Hmm?  "Memory deficient"? Oh, woe.

  I know I have some "pieces" from about 3.5 that are truly mine--because I've never told anybody else about them and nobody "reminded me" about the time that ______ (fill in the blank.)

The best reason to take  kids younger than 4 on big travels?  Cheaper than paying people to care for them back home.
