My 4 year old (5 very soon) is a very self directed learner. He can't seem to put his shoes and socks on but he can tell me most of the flags of the world (lol). He has a passion for a subject and almost gets obsessive about it. He has taught me about so many flags, hence the flag counter on my blog. He gets so excited when we have a visitor that adds a new flag.
Watch it fizzle.....
... and have fun.
