As my favorite professor used to say, "I've forgotten more than you've ever known." ?I'm not making light of memory problems that might be symptomatic, but I still agree with the idea that once you have 65 or 70 years of memories to retain, the attic gets a little full, and it takes you longer to get to any particular item. A five-year-old has about twenty things to remember, so clearly he or she has little problem with it. And no one cares whether the little cutie remembers anything or not.
